If I were asking $3200 for a 1988, it had better be in excellent condition, everything working, and been stored inside when not in use for it's entire life. We paid $1800 for a 1986 and I think we over paid, considering the amount of work we had to put into it to make it useable. (See blog in my address below if you want to see what was needed.) If it's been for sale a while, he might take less, but I'd definitely look it over with a fine tooth comb and politely inform him of the blue book before negotiating. If it is in excellent condition with no water damage, you might get it for $2800ish. As always, my opinion, YMMV.
