Client Testimonials for RS Motorwerks

I recently needed some serious transmission and engine work done on my 996 Twin Turbo. I was caught between spending a fortune at a Porsche® dealer or risk taking it to someone who may not have the Porsche experience to do it right. When it came to RS Motorwerks German Auto Repair, I was immediately impressed with their expertise and forthright honesty. Their analysis of the problem was excellent. Their expertise in fixing the issues was outstanding and throughout the process of fixing my car, their communication was perfect.

My 996 now runs and performs better than new and I could not be happier with my choice of RS Motorwerks. I feel I got excellent service and saved thousands of dollars at the same time. They will get all of my future Porsche business.

I am belatedly writing to express my sincere thanks and appreciation for your counseling and suggestions, and equally important, your actual servicing and “re-awakening” of my [1970 Porsche 911]. I am more than happy with the final product.

As background and reminder, I bought this car in NC in 1987 to keep and restore over time as a collector’s car. I have had the engine overhauled twice (the last time being in 1995),the car repainted, new carpeting, etc., but the mechanical fuel injection component never seemed to stay tuned. For the last 3-4 years this car has been “hibernating” in my garage waiting the perfect day for a drive. I checked out several shops locally before first meeting with you. I was very impressed with your knowledge of Porsches in general and this model in particular. Most importantly, I was impressed with your suggestion to consider swapping out the old mechanical fuel injection for a new PMO 40 carburetor kit. I deliberated a bit about keeping the car pure or making the car run more reliably, as you suggested. The latter won out and was the right decision.

My 911  not only runs great now, the acceleration and dependability are much improved from what I remember from my old system. Finally, there are numerous secondary tips and improvements you also suggested such as tires and shocks, single battery, etc., which have all resulted in bringing the fun back again in driving this 46 year old classic.

A Very Satisfied Customer – Terence A. (Terry) Walts

Testimonials pageI own a 1970 280SL Mercedes. I’ve had it for 15 years and drive it to work daily. For the last four years, the car hasn’t run well. It misfired and hesitated. I’ve spent thousands trying to fix the problem, using numerous mechanics, until finally, someone told me about John. He diagnosed and fixed the problem. He’s like the doctor on that Fox show “House”, but instead of solving medical mysteries, he solves mechanical mysteries. I highly recommend John Herzler and RS Motorwerks. In addition to being an excellent mechanic, he’s also a nice person.

I wanted to take a moment to thank you and your father for the work you do on my 1968 280SL and the wonderful customer service. Since having the car restored by Bud’s Benz, I was referred to you for continued service. You are not only convenient in the Sandy Springs area but also an absolute expert. I drive my car with confidence and enormous enjoyment. I thank you both very much.

Sincerely, Jeffrey B. Bogart, Esq.
