Looking at a 185S, guy says its a 1985 but I only find info to 1983 on 185S. The thing has sat for two years and doesnt start now, he says it ran good when he parked it after getting a 4 wheeler. It needs 2 tires and a good cleaning, it also has been painted green and should be repainted. The fenders are in good shape and it has the back rack and trailer hitch. Any things I should be looking for that were trouble on these trikes? Whats a fair price to give? Thank you for any help.
