Bought my C55AMG from a friend and I am very happy that I did. Incredibly fun to drive, has a sports car feel with a European sedan look. It is a real sleeper except to those who know AMG, and I am surprised how many people know AMG. Ride is a bit stiff but the handling makes up for it. I'm getting 22+mpg on the road and 19mpg around town if I'm not on the gas.
Nothing else can compare this this car's power. That is about where it ends for me. Within two weeks of delivery the remote access FOB features quit working and the radio was in a constant state of static and random on off behavior. A warranty trip to the dealer and the radio was fixed and they said the keyless access was fixed as well. The keyless access quit working two days later and this was followed by a HUGE transmission fluid leak in my garage and a mysterious flapping sound coming from the engine compartment. Back to the dealer again. They advised they leak in the tranny was a common problem and they could not find the mysterious noise after numerious attempts.
I am retired and wanted a own a car that would be fun to drive and purchased the C-55 AMG model. I drive it to San Diego twice a year a distance of 1300 miles each way and will drive for a period up to 12 hours a day.I enjoy the drive and never get stiff or sore from the long hours. The car looks and runs great with all the power I need. I get lots of compliments on how good it looks.
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!
I originally bought this vehicle because my wife would not let me buy a E39 M5 due to the manual transmission, so I had resigned myself to a life of commuting boredom without my beloved 3rd pedal. "At least I'll have the big V8 to listen to while I wait for the transmission to catch up to my right foot" I thought. Well, I was wrong. The AMG SpeedShift is extremely impressive in daily use; it is very rarely in the wrong gear and is tuned for an enthusiast driver. Sport mode is very entertaining and Comfort isn't a blatant sacrifice to the EPA mileage gods. This, coupled with the prodigious amounts of torque and deep exhaust note, make for an entertaining drive even in traffic.
