see when the last timing belt change was. I wouldn't let that scare me away from one, but would suck to have it snap right after picking the truck up. If possible, remove the upper art of the timing belt cover and inspect it yourself. If not when checking the truck, shortly after purchasing....better safe than sorry.
Other than that, nothing I can think of. I loved my 90 model, and love my 86( well if I would put it back together ).
