If the C63 came with a stick or a DCT I would have gone that way. I'm not fond of slushboxes though and while the one there seemed as good as I have tried I just don't like em. And yeah, I know all the numbers, just don't like em, its an opinion.
In fairness however the dealer would not let me flog the car so it was hard to get a good feel for it. I know it sounds bizarre but I'm thinking of checking out the E55 when it shows up in 14 with the DCT. That may be my new daily.
