Thinking about Buying a Used Porsche Boxster?

Thinking about Buying a Used Porsche BoxsterAre you thinking about buying a used Porsche Boxster? At Shaus Motorsports in Aurora, we like the Boxster, because in all its generations, it has enough talent for the serious drivers and enough style for the Sunday fun crowd. Here are a few notes if you’re thinking of adding one. Boxsters can be quite affordable which makes them appealing. Here are a few things to keep in mind when you consider buying one.

First Generation (1996-2004)

There is a lot to appreciate about the first generation of Boxsters. It was a runaway success for Porsche. It had the style that Porsches were known for while keeping its racing engine and excellent handling. Though some Porsche enthusiasts of the time may not have viewed it favorably, the first generation Boxster was a big success.

If you are thinking of buying a first generation Boxster, check for oil leaks because the rear main seal is known to fail. Though the seal is inexpensive, the labor to get to it can be a bit pricey. Keep in mind too that the early first-generation engines had intermediate shaft issues, specifically the dual-row bearing. If and when it fails, the engine will need a rebuild, which is not a cheap endeavor.

Other areas to check include the main oil seal, the clutch and bearing, the cylinder heads, ignition, and water pump. While that may sound like too much, there is a high probability that a previous owner has already addressed many of these issues, so don’t let the list deter you.

Second Generation (2005-2011)

If you're thinking about buying a used Porsche Boxster, the second-generation model was considered evolutionary. These Boxsters had both increased horsepower and torque. They also included better technology, greater efficiency, and direct fuel injection.

Many of the first generation engine issues were solved so potential buyers need to check the usual suspects: accident repairs, uneven tire wear, and service history. The only issue that sticks out for the second generation is the suspension springs. A broken suspension spring should be pretty easy to notice—one corner of the car will be lower during the test drive or you will hear a noticeable noise.

Pre-purchase Inspection

Like many other cars, a comprehensive pre-purchase inspection is a worthwhile investment. Be sure that the inspection includes a laser wheel alignment check, which will potentially show you if the car has been in an accident and whether the repair was up to standard.

Be sure that the Boxster includes the windbreak between the headrests, the roll bar inserts, both sets of keys, and manuals. These items can be easily overlooked and are expensive to replace. Ensure the fabric roof works properly and is in good condition. Don’t skimp on doing your homework. There are a number of Boxsters on the used-car market and you want to make a wise choice.

Are you thinking about buying a used Porsche Boxster? We can perform a pre-purchase inspection or look over the one you already own, here at Shaus Motorsport in Aurora. We can help you figure out if the Boxster is in need of some work or if it is ready for you to enjoy out on the road.

BMW is Working on Autonomous Cars

BMW is Working on Autonomous CarsAt Shaus Motorsport in Aurora, we’ve been keeping up on the news that BMW is working on autonomous cars. As you may know, BMW is making big waves in the car world with their 2017 5 Series because it makes a significant advance towards driverless vehicles. Though there are enthusiastic supporters of these cars, some BMW drivers are not keen on giving up control behind the wheel. After all, these vehicles are exhilarating to drive which is why people buy them.

Now that BMW is working on autonomous cars, we’re getting more details and seeing a number of benefits that might sway the skeptics. Take a look.


The biggest advancement is the Car-to-X-app. Why? Because many proponents of autonomous driving believe that cars need to communicate with each other in order for driverless cars to work safely and accurately. The Car-to-X-app allows the 5 Series to share its information with other BMWs. It is the culmination of the work of the 5G Automotive Association which includes BMW and other car manufacturers as well some of the leading telecommunication companies.

Remote Control Parking

One of the fun features of the 2017 5 Series is that you can park your car much like you would park a remote control toy car from your childhood. This will help when a driver needs to fit into those spaces that just won’t let you open up the driver doors. Just step out of the car, guide it in, and when you need to leave, use the Remote Control Parking feature to guide the car back out again.

Semi-Autonomous Driving

The semi-autonomous system is supposed to help avoid accidents. This system warns the driver of a potential on-coming collision so that they have an opportunity to maneuver away. Additionally, the system will pre-condition your brake system, as well as steer and accelerate up to 130 mph. The system is also designed to help avoid speeding tickets by automatically adjusting the speed to a max of 9 mph above the determined speed limit.

Driver Assistance Plus Package

All the new capabilities are part of the 5 Series Driver Assistance Plus Package. Basically, BMW took the Active Driver Assistant and put it together with the Driver Assistance Plus II to create the Driver Assistance Plus Package. In addition to all the features we already listed, this package will perform lane changes, keep the vehicle in its own lane, and avoid obstacles. It also assists with navigation. All these features make the 2017 BMW 5 Series a very exciting step forward in driverless cars.

Ultimately, driverless cars are something to be excited about and it is wrapped up in a classy car that offers a great deal more in terms of technology. Now that BMW is working on autonomous cars, we plan to keep an even closer eye on their next step too—we certainly want to see what will be next.

If You Drive a German Car, You Need a Higher Octane

If You Drive a German Car, You Need a Higher OctaneAt Shaus Motorsport in Aurora, we caution our customers that if you drive a German car, you need a higher octane. This is not just a guideline or suggestion, but it really is the way your high-end engine is designed to run. If you ignore this rule, you run the risk of expensive damage to your engine and your bank account.

Premium Octane is a Necessity

Why does your German car need a 91 or higher octane? Simply put, German vehicles are built for high performance and use a higher horse power than your average engine. German engines are considered to be high compression engines. These engines, when running on lower octane fuels, produce uncontrolled combustion called a ping or a knock. Over time, knocking can cause serious damage to your engine. The higher the octane of your fuel, the better the fuel’s ability to resist knocking.

Saving Money in the Short Term can Cost

High-octane fuel can be pricey, particularly in summer when fuel prices rise. It can be quite tempting to reach for lower octane fuel to save money. Initially, you will not notice much difference. It may even seem like your engine is adjusting to the lower octane fuel. In reality, your vehicle engine is suffering a slow and steady beating.

Understanding Octane

It is important to understand exactly what the higher octane does. Higher octane does not have more energy capacity than regular fuel. It has a much higher resistance to knock. Knowing this advantage, German car manufacturers design engines with maximized performance, using the higher octane as protection from the premature fuel combustion (also known as pinging or knocking) that comes with maximized performance. The engines can pull out more power from the gasoline and still remain protected. The maximized engines require the premium octane because they were built knowing the higher octane would protect the engine.

Knock Sensors

If you have a newer German car, you may be thinking that you can simply rely on your knock sensor while using a lower octane and all will be well. The knock sensor does help. If the sensor detects knocking, it detunes your German car engine until the knocking ceases. This protects your engine to some extent. Your engine has still taken a beating until the sensor has completed the level of detuning needed. Once the detuning has occurred, your car’s fuel mileage will take a nosedive and your engine performance will suffer as well. In essence, this will negate any savings you may have obtained at the pump.

Ultimately, if you drive a German car, you need a higher octane. Saving a few cents at the pump can cost thousands in engine repair. Avoid the long term cost by using the correct octane for your German car. If your Audi, Porsche, Volkswagen, or BMW needs some TLC or has developed a knocking issue, contact us at Shaus Motorsport and we will take good care of your vehicle.

Are You Using Your Car AC Correctly?

Are You Using Your Car AC CorrectlyAre you using your car AC correctly? With the high heat of summer, Shaus Motorsport in Aurora helps a number of BMW, Volkswagen, Audi, and Porsche owners with their car air conditioning issues. Fixing these issues can be pricey so if you take good care of your AC, you often can avoid a costly repair while easing the strain on your engine and increasing your overall fuel efficiency.

Check out the following guidelines to ensure that the efficiency of your AC is maximized while conserving fuel and saving your engine on your BMW, Volkswagen, Audi, or Porsche.

Take Advantage of Shade

On hot and sunny days, park your vehicle in the shade. This will keep the inside of your car cooler. The cooler your car is when you start driving it again, the easier it will be to make the internal temperature more comfortable at a faster pace. All of this eases the strain on your AC.

Roll Down Your Windows

Take advantage of the sunny day by rolling all your windows down and letting the wind blow through your hair and your car. The internal temps of your car can get much hotter than it is outside. Letting the hot air out before running the air conditioner will help cool the inside of your car faster.

Use a Low Setting to Start

Cranking your air conditioner right away is a good way to wear out your air conditioner faster while straining your engine, and lowering your fuel mileage. Start your air conditioner on low and allow it to run on low for a while before blasting it on a hot day.


Re-circulating your air will help lighten the load on your vehicle’s air conditioning. When you don’t re-circulate, your air conditioner has to work extra to keep you cool. This increases the wear and tear and affects your car’s engine and mileage.

Turn Your AC Off First

When you arrive at your destination, turn your air conditioner off and leave your fan running at medium speed before turning off your car. By doing this, you will help keep your evaporator dry.

Fuel Efficiency

Using your air conditioner lowers the fuel efficiency of your vehicle. The higher you are running the air conditioner, the lower your fuel mileage will be. If you want to save fuel, limit your air conditioner use, lower the level of your air conditioner, and follow our other tips as well.

Get Your AC Serviced Annually

Having your air conditioner checked over regularly will help ensure that it works well on the hottest days of the year. Be sure that your refrigerant levels are checked as well because this is not always included in standard service checks. Use an auto center you trust to service your BMW, Volkswagen, Audi, or Porsche, like Shaus Motorsport in Aurora.

Are you using your car AC correctly? Using the above tips will help you save your AC and your car. If you have a BMW, Audi, Porsche, or Volkswagen AC issue, call us at Shaus Motorsport in Aurora to get your AC working properly.

Getting More Mileage Out of Your BMW

Getting More Mileage Out of Your BMWAt Shaus Motorsport in Aurora, we want to help you with getting more mileage out of your BMW. These vehicles have some of the best performance engines in the world, but it is easy enough to skip some simple steps and not get the most out of your BMW engine. Here are some tips to extend the life of your BMW engine and increase its overall performance.


One of the simplest steps is also the one that often gets skipped. Change your engine oil and engine oil filter regularly. For older engines, changing every 5,000 miles is an excellent schedule to keep. Newer models that use a full synthetic oil can go 7,000 miles between engine oil services. If you are not sure about the oil your engine requires, check your owner’s manual or visit us at Shaus Motorsport in Aurora. If you have an M-Series engine, it is important to only use single weight oil. Do not use variable weight oil as a substitute.

Oil Filter

When it comes to getting more mileage out of your BMW, your vehicle's oil is crucial. It is important to know that not all oil filters are created equally. A lot of fast lube shops use cheaper paper oil filters. These types of filters can have issues with air restriction and frequent clogging. These cheap filters should be avoided to extend the mileage on your BMW engine.

Pay Attention to Your Cooling System

Make sure that your engine has the coolant it needs and that it has enough of it. Getting more mileage out of your BMW requires proper care and attention to such an important but easily overlooked part of your high-performance vehicle. 

Use a Specialty Shop

Shops that cater to higher end cars and engines, such as Shaus Motorsport in Aurora, are your best bet in keeping you satisfied and your engine running in top shape for a long time. A trained BMW specialist has a much deeper level of understanding and a visual inspection of your engine will give them the opportunity to catch issues early, long before the issue becomes a costly repair or leaves you in a tough spot with a car that won’t start.

Pay Attention to Your Check Engine Light

Though there are many, many reasons that your check engine light comes on while driving, do not be the driver who ignores it. There are three main reasons that prompt the light to come on: fuel distribution and flow, air distribution and flow, and spark delivery to the combustion chamber. Some reasons can be quite simple like your gas cap isn’t sealing properly, but some can be an indicator of a much more serious problem. Ignoring the light can cause your engine serious damage and can put a serious dent in your wallet.

At Shaus Motorsport in Aurora, we want you to know whether you are getting more miles out of your BMW. These simple steps are a good start to extending the life of your engine. If you want more help and tips to keep your engine in top shape, contact us a Shaus Motorsport in Aurora.
