Between the C63 AMG and Audi RS4, without watching this video and getting the specs, performance, and ride. My choice is the Audi RS4.
It looks luxurious (C63 looks great also but knowing the C-Class has been redesigned, it’s dated), interior looks more suited for me, and it has Dual Clutch transmission.
Motortrend’s Head to Head episode great points between the two cars… In the end he makes his decision which he would choose.
Do you agree?
