Would definitely get CPO from dealer or find out about extended warrantee; they're probably the same thing as there are deductibles on CPO cars after the standard warrantee expires. I bought a 2000 323 cic in 2002 (CPO) and had no significant problems with the top or the Steptronic. The A/C / Heat occasionally didn't seem to function right, but it wasn't constant and I never tried to get it fixed; I think I have heard of others with this glitch, too. They could never fix the rear speaker rattle I had from the start either. When I got my 04 330, it felt "tighter". It wouldn't surprise me to start to experience little electrical problems after 4-5 years, as I've heard the German cars have this quirk, too.
