I have test drove a SL550 and drove my friend's M6 coupe before.
The SL550 does not seem the right vehicle for me. The interior is nice but same as I felt in the CLS, it's kind of cold feeling. However, when I sits in M6 Coupe I thought I was really going to drive a super luxury performance car.
For driving: these two cars also feel different. Even M6 is not a small car, but it does feel smaller than its size, but Sl550 did not give me the kind of feeling.
If I am in this market, definitely I would go with M6. However, SL550 is also a nice car.
If you wanna drive a car slowly in the downtown for kind of status, get SL550.
If you wanna get a car for comfort performance and eye-catching.M6 will be top choice.
just my two cents. Can't go wrong with either.
