During Spring Event last weekend we saw this Mercedes C63 S AMG Coupe which has been heavily modified by GAD Motors. It has over 1000HP and the drivetrain has been converted from RWD to AWD (4Matic+). In this video you can see it making some revs, accelerations and drag races against an 800HP RS3 Sedan, Quicksilver R8 V10 and C63 AMG Estate.
