2006 Mercedes-Benz C-Class C55 AMG 4dr Sedan (5.4L 8cyl 5A)
This car is very smooth. I don't tend to use the car as hard as I did my 540 with a stick but the power and performance is there. Certainly it has a stiff suspension but I have found it civilized. Interior is confortable and functional. I love some of the details like contrasting stitching and suade details on the seats. Basically, if you want a really civilized car that can has heavy duty performance underneath the surface this is a great choice.

I'm very happy, if car has bluetooth I have not found it. Also, gas tank is a little small for how fast this car uses up gas. Tank warning light is not obvious and I have gotten close a couple of times.
