I wouldnt buy it.... you're going to wind up putting $$$ in it and then its still jsut going to be $500 ish quad if you ever sell... my neighbor had a 85 and it was the biggest POS, completely unreliable.. he only keep it a few months, but he must have spent $3-4k on that thing and only sold it for $1100 (this was back in ~95 or so)
87+ are much better investment.. if you're really wanting an LT, go checkout quadracerhq, some good deals over there...
