1. Please don't take this the wrong way - you have the desire for this pile of posh pre-owned sheet metal - run a carfax and pay an indy mechanic to look at it. Could save you thousands.
2. Shop around - like
www.statewidelist.com, which will search all of craigslist in the state of your choice for Rover and sort by city. Handy to see what is out there and how much.
3. Receipts for work or parts like head gaskets, oil pump, drive shaft are all pluses.
4. We have plenty of owners who joined here with a truck they purchased within the last few weeks, only to have head gaskets, overheating, etc.
5. Your research may point you to another year, based on potential problems, availability of CDL, etc.
