The merc is all about the presence, noise, effortless grunt, the badge, the comfort. A motorway cruiser. I see the appeal in a non too serious way. I nearly bought one instead of the TTRS. If it wasn't all about performance for me, I would have has the merc instead. More car for your money. Got a c200 blue efficiency and that car is a pleasure to drive in the fact it's so relaxed and a nice place to sit inside.
