"RENN HAUS performed their ECU upgrade/flash on my Mercedes with a K&N air. Results were a healthy increase in horsepower (25hp) with a boost in acceleration especially in 2nd through 4th gears. It is a lot more fun when merging on the Interstate now. Off the line acceleration has improved and highway cruise gas mileage has improved. Normal driving is seamless, smooth and transparent to the driver. But put your foot into it and the result is immediate and smooth. The responsive interplay between the ECU management of the engine and the 7 gear electronic transmission results in GO! GO! GO!!!!!

GUY COVINGTON and his folks at RENNHAUS made this customer happy!!!!!!!"

“Great, trustworthy experience

I heard about Renn Haus through a friend who had a great experience with his Mercedes service. My experience was no different. Guy and Stephanie have helped me maintain my E500 through careful review and explanation of each service repair. I have recommended Renn Haus to other friends and co-workers and will continue to do so in the future."

Thanks for the good news about Pete. I just visited your office on Friday and the first person I saw was Pete and he called me by my name! He is truly dedicated to serving customers and he does it well. You couldn't have chosen a better man than Pete.

Best Wishes,

"Renn Haus gave me the real truth on the necessary repairs for my 2004 CLK500 and saved me over $2,000.

The starter on my car stopped working so I had it towed to one of the largest repair facilities in Sarasota. They gave me the estimate to replace my starter along with an estimate to repair my dangerous front end suspension that totaled over $2,000. This didn't seem right to me as my car has only a little over 45,000 miles. So I had that shop fix the starter and took my car to Renn Haus to look at the suspension. Their technician could not find one thing wrong or needing to be replaced on my front suspension and Renn Haus didn't charge me for their time.

So from now on I will refer all my family and friends to Renn Haus."

"Great experience...

Guy Covington and the people at Renn Haus are passionate about their business and their customers. I brought my 2005 Mercedes SL 500 in for a minor repair on the retractable hard top. They tell you just what you need and the cost. They do not try to get you to do things you don't need. They had the part the next day and it was fixed perfectly. They make getting your car repaired a pleasant experience. I will not take my cars anywhere else."

“Courteous and Professional

We are in West Florida on vacation and have our 2002 Audi A4 with us. While on a daytrip to Miami, our car began making ugly noises. After a phone discussion with Guy at Renn Haus, we had the car towed back to his shop for repair. Guy was extremely nice and went out of his way to help us. He even arranged for a rental car to be delivered to his shop since we were not expected until well after 5 PM. After a thorough exam and review, the problem was diagnosed and repair completed. Guy and Stephanie were courteous and professional throughout. The shop is spotless. What started out as a harrowing experience ended with smiles. We would recommend Renn Haus absolutely."
