I've heard other people say this...what were the problems with the pre-2001 models that were corrected in '01?
They updated the engine, fixed the suspension issues (mostly first year), and some other small items. 2001 was also the first year Stabiltrac was standard so that alone was worth it IMO. But 2001 had the most updates/fixes of any year for the C5
