Mercedes are granddad cars, especially the saloon/sedan versions (at least the station wagons/estates are bought for practical reasons!) and even the early AMG versions, especially since all poverty spec models now have an "AMG" trim level, minus the engine, suspension, brakes etc.
Give me a BMW (330, 325, M3/5) or Audi (S4/5/RS5/6) any day over any Mercedes.
Yes the V8 and V12 AMG Mercedes are fast but what else is there that's fun? Boring. Dull. Old.
Hell. I've had more fun in a 318 (1600cc) BMW than a V8 SLK. Zzzzzzzzzzz
I do like the older Mercedes, 50s to early 80s.
