Is a not well known Mercedes-Benz preformence company which is twice the price of AMGs. They deliver great HP and style.
All though they can be a bit costy.
Hey look i just got my RENNtech S-class. Sweeeet dude.
Renntech is another tuning company for Mercedes-Benz, just like Brabus. You can Renntech an AMG (i.e. Renntech S55 AMG).
I personally like Brabus over RENNtech, but both are excellent companies that do great things for a great car.
