Our technicians are an integral part of RENN HAUS. They are fellow enthusiasts with the same passion. Each technician always asks himself when working on every car, “How would I do this if this were my car?” They then apply that principle to every job. That integrity, honest communication and work ethic have created trust between RENN HAUS and the car owners, most of whom have become long-term customers and friends.

Give us a call, come by the shop, or visit us at the local race track. We will be happy to share with you our passion for these wonderful automobiles.


So if you live anywhere in Florida or close by in Sarasota, Bradenton and Venice … stop in and let’s talk cars.

Mercedes & Porsche Customer Testimonials

"If you want the best, look no further, this team knows everything there is about Porsche’s. I had several issues with my 1994 3.6 Turbo due to a bad wreck it was in. We discussed the problems, what was needed, the time that it was going to take, then Guy Covington, the Service Manager ,discussed the costs and I must say they were very reasonable and the car was completed on time within the estimated cost and the car is 100% perfect."
