2006 Mercedes-Benz C-Class C55 AMG 4dr Sedan (5.4L 8cyl 5A)
This car is fast! Let me rephrase that, it's VERY fast. The car should be driven for fun, not for comfort or fuel economy. The ride is very stiff, but that's what you want in a sports car. Don't bother looking at the mpg's (11-14 city, 18-22 hway). Interior build quality seems below my old 1997 C230 which is a bit disappointing for a sedan that msrp's for 60K. There is a lot of plastic on the dash, and most controls feel cheap to the touch. But who cares? This car is FAAAAAST!
Brutal acceleration! Unique front end that looks like the CLK. Sleeper look. The instrument cluster is pretty nice, and interesting since it doesn't follow the traditional Mercedes center speedometer look.
Operating a moon lander is probably a simpler task than to figure out how to enter an adress in the NAV system. The AMG seats, although look very cool, are not very comfortable, especially on long trips. Interior materials and build quality are worse than the C- Class 10 years ago.
