I'm looking at a '91 suburban to purchase as a family hauler. No minivan for me! The guy is asking $3500. It has a rebuilt 305 with <5,000miles and rebuilt 700R4 with about 15,000miles. It is lifted with 35s. It has AC but it does not work. The compressor is not seized, at least that's not the problem. A few dings, no rust. I haven't driven it yet, and I'm looking for any advice on what to look for. I know the usual GM stuff like the cracked frame @ the steering gear box. Is there anything else different to look for in suburbans? What do you think about the price?
