i just bought a 2000 clk 430 and i have trouble putting the top up and down. it is making me crazy. i have no idea what is wrong, but now its down and i cannot for the LIFE OF ME get it back up. even the roll bar is stuck now. argh!!!! i'm so upset...i've only had the car for a week and already so many problems with the top. are other people seeing this as well. any ideas on what to do? thanks!
