If you PM to me your email address, I will send you a pdf file of all the updates from 1990 to 1996. There are 15-20 per year, a lot of little things that all add up. The main updates I see that are important in my opinion, were in 1991 and 1992 with increased horspower and the "power boost" engines. I would stay 1992 or newer. The drink holder became standard in 1995 if that is important to you.
