\'77 Jimmy W/ 87K original mile (Good buy? Problems to look for?) Haven't seen it yet, but its a one owner. Says it has a little rust, but not very bad. Anything problem areas i should look for? He says its all original, except the motor was rebuilt a while back. He wants $2000 for it. I really would like an 81 or new, but this is more my price range. Any problems with the older Jimmys? What do you think?
