i currently have a bmw e46 3 series convertible. i hate the 3 series due to all the problems i have had with my current car and the coupe i had before. i am VERY close to buying a w209 clk 320 this week. can anyone give me some insight on these cars as i have little knowledge about mercedes. i always hear that the quality is going down and mb's have a lot of mechancile problems too. im 24 and have only driven bmws since i got my liscence...so i have no idea what i am getting myself into. any help will be appreciated. thanks in advance.
