We are “The Dealer Alternative” for your German Car


It’s been said, “It’s cheaper to maintain them than it is to fix them.” A car is like most things in life; if neglected they will deteriorate, become unreliable, break down, and put you in a bad situation. At GermanTech MotorWorks we can’t stress the importance of your plan enough. Do you want to sell the car next month? Do you want to make the car last just two more years? Do you want the car to make it to 300k miles? Do you want your car to make 500whp and be a daily driver? These are all questions that every car owner should know and share with us. We want to build you the most optimal plan to achieve the goals you have in mind. The worst thing you can do is to put off maintenance and problems until they pile up into a list that takes thousands of dollars to rebuild. Why? Because then you’re stuck with a car that is in shambles and is also worth absolutely nothing to potential buyers as a result. Let us help you keep it maintained so that everything works as designed regardless of the number of miles on the odometer. By mapping out the required maintenance and heading off the common issues with your model, you will save thousands in repairs that may have been preventable in the first place. We also have financing available if needed. This is usually still much more affordable than buying a new car.


In a perfect world, all good things would last forever. That said, we all know that’s not how life works. The next best thing is to know that you have a team of trained experts to help you with your problems when they do arise. Reliable people looking out for your best interest and doing quality work at a reasonable price. Any repairs performed by GermanTech MotorWorks also carry a two year warranty on parts and workmanship. You can also rest assured that in the event of an emergency, you can always bring the vehicle to us without an appointment.


If you’re like most of us, you will spend over 6,500 hours of your lifetime driving. A lot of people don’t give this much thought and are happy with a reliable car that suits their needs, and there is absolutely nothing wrong with this; however, there are others who want more from their daily commute. They enjoy the winding roads, the lone straight stretches, different wheels, and modifying various other features. If you are one of these people, you are not alone and we can help. We have relationships with many vendors who we work with daily to provide upgrades of all kinds for our customers. Some of these include: Steve Dinan’s Carbahn, Malone Tuning, BM3, MaxPSI and Tire Rack. Whether you know exactly what you want and simply need assistance installing, or you have an idea of what you want but would like to discuss options, we can help.

Why Clients Love Us

Brian Reed

I’ve worked with owner John Kephart for years and trust him with my BMWs and Mini. He knows his stuff, but just as important you can trust him! Highly recommend.

Rafael Cotto

Took our 1990SL with a soft top that wouldn’t close. They were able to figure out the problem and got the top working by replacing a group of parts that were bent. Other than having to wait a week for some of the parts to arrive from Germany the car got repair quickly. Fair price for good accurate service!

This mechanic shop is in a great location, right off Hurstbourne/Plantside area. I feel like I can trust them not to rip me off when giving me advice about my car. I definitely will call them again if I need any work done on my BMW. This place provided a second opinion & $800 saved – I’m glad I got it.
When I took my car in, they provided clear information & I had my car back in no time. I will recommend them to anyone I know that drives a BMW, Benz or Mini.
