This is a 2014 CLS550 600HP MONSTER. This car has been my baby and has been treated as such. With high miles it of course ran into Airmatic and engine issues. All of these issues have been dealt with including leaks and airmatic. I have replaced all of the bags, the compressor, 2 lines, and the control module. The car has 2 Renntech tunes; one in the engine, and one on the bags. Not sure on the bag tune now due to the compressor being brand new. This car is said to last for the rest of the bodies life. Every single issue except for the custom wheels being shipped has been fixed on this car.
