Matt Farah and the TUNED crew wrap up their East Coast tour by visiting RENNtech tuning center, an unassuming workshop in which some of the craziest tuned Mercedes cars are made. After a chat with RENNtech boss, a former AMG engineer, Matt takes one of their latest creations for a spin. It’s a 700-hp Mercedes CLS63 AMG featuring RENNtech’s unique body kit. It’s a work in progress, but my God is it awesome.

You can tell by the size of that grin on Matt’s face how fun this car is. It costs a 120 grand, but then it does things not many cars are capable of. This luxury Merc can do a rolling burnout at 40mph while giving you a butt massage! And the way it sounds… un-freaking-beliveable.
