I have a 86 735I that I have had for over five years now. When I got it it had 145000 miles on it; it has over 200,000 now with very little work. Their are some commen problems though, I tried to charge my a/c last year and let the car run for a long time tring to get it to take the freon and the next day my transmission started going out, the pump in the transmission only works when the car is moving so keep this in mind. Parts are hard to find sometimes,some can be found at your local chane store but some have to still be bought at the dealer. I actually have two 86 735I's,I paid $1500 for the first and $650.00 for the second one. If it were me I would not pay over $3000.00 for it unless you just have to have it. Thats just my two cents worth thank's autogunner.
