Service, Repair & Tuning MERCEDES, PORSCHE, BMW & MINI
Personal Service, Outstanding Value & Finest Quality
RENN HAUS has over 50 years of combined experience in servicing and repairing MERCEDES BENZ, PORSCHE, BMW AND MINI as well as other fine German automobiles.
The Renn Haus staff takes the time to listen to each owner’s concerns in order to determine the best solution for every customer. Our technicians always ask “If this were my car, what are the options and what is the best solution?” We then present those options to each customer for approval.

Our 30+ years of experience in tuning and performance modification is second to none. Our tuning provides the best performance possible for your car without changing the driving dynamics you love.
Our technicians hold certifications for Automotive Service Excellence (ASE) Master Technician, Mercedes Technical Specialist, BMW Technician, Porsche Specialist, Mercedes SLR McLaren, Mercedes G-Wagon, Mercedes Diesel and many other system specific certifications.
RENN HAUS has many years experience serving the Sarasota, Bradenton and Venice areas. Moreover, we are considered one of the top companies for tuning, modifying, fabricating custom exhaust systems, transmission rebuilding and engine rebuilding in the Unites States.
As an example, our RENN HAUS tuned Mercedes Benz E55 AMG has 600hp, 630lbft of torque, runs the 1/4 mile in 11.536 seconds at 120.53 mph and goes 0 to 60 in 2.99 seconds! RENN HAUS can turbocharge or supercharge many cars including correcting tunings and modifications from other company's that did not meet the owner's expectations.
After experiencing the customer service excellence of Renn Haus’ team, I will not be taking my BMW anywhere else for service. Honest assessments, fair estimates, and a welcome experience from every member of their team--owner to technician—are the reasons why.
Thank you Guy and team!
