READ OUR CUSTOMER REVIEWS

"After years of owning my Porsche and going to multiple shops with horrible repairs that led to different problems, I've learned my lesson and now stick to the real professionals: German Performance."

"Can't recommend Marc highly enough."

"These guys are the real thing. Marc has material Porsche and BMW racing experience, yet treats you like you'd expect from your neighborhood mechanic."
