"I've had the C63 for 9 months, and love driving it. It puts out a great exhaust note, and can definitely get up and go...you need to make sure you are pointing in the direction you want to go when you hit it. It also has some nice features, and I love the COMMAND Nav...it is VERY intuitive and easy to see. I've had many compliments on the display.
I would argue that for the money, though, there are other cars that may be worth the purchase. While I have easily been able to beat Mustang GTs and STis or Evos on the highway, I'm a little disappointed at the low end speed. I had a BMW 335i stay with me until 4th gear the other day...a car that I thought I should have crushed for sure. Also, I'd hate to get into twisties with a BMW, as the C63 feels very heavy in corners.
Overall, it is a great car, and I love that there are few out there (only have seen 1 other, different color, in all of Oahu). I do think you can get more for the money...but then, it wouldn't be a Benz."
"Love my C class since I bought it in 2008. I have the luxury model with package 2, and enjoy every day of driving it. It is beautiful, queit, comfortable, very smooth and has a many nice features like folding mirrors and heated seats, ect."
"I'm so glad I went with this car. After months of looking I settled for this car because of it performance and of course the name. The only thing I would add or change about the car is the noise level when driving. It could be a little less noisy. Also, no sound when the blue tooth is engaged. Otherwise I love it."
