Opinions on the C36 and C43

[mbsickness]

Hello everyone, I have been cosidering a C36 or a C43. I would like to get your opinions on which one is preferred and what are weak areas of these cars. It will be a daily driver and will have many miles (100 miles a day) logged onto what ever the car already has. Most I have seen typically have between 75 and 95K miles....I am assuming that these cars carry on the MB tradition of being good for at least 200k miles. The only thing that I have heard is that the C43 isn't really faster than the C36 as the C43 gained some weight with the additional two cylinders. Any and all insights would be appreciated.

Thanks.
