I would just look for the usual stuff like a good service history, general all round condition, no excessive body damage. The engines fitted are good solid lumps and will stand the miles no bother, but maintenance is essential just like any other vehicle. It shouldnt make any strange noises, no excessive smoke of any colour, a bit of black smoke on start up is normal, and also if you rev it hard.
If its clean and tidy, shows signs that it has been well looked after, and a good history then it should be a good buy. At 130000 you need to be checking that the engine belts have been replaced as well. I cant really advise on prices, they seem to be all over the place depending on where you live.
There are some members on here with starship mileages and no trouble.
Be choosy, there are lots of Connects about so make sure you get a good one.
