The Car Connection's Take
TCC Rating
8.8
9.0
TCC’s Bottom Line
The 2008 Mercedes-Benz C63 AMG sports a fluid ride, spot-on handling, and shrieking power to make it the most accomplished C-Class ever built. The 2008 Audi RS4 sedan and cabriolet bring rocketlike power and price tags to the otherwise humble A4 lineup.
