I'm looking at buying a 1982 2L air cooled, although the mileage concerns me. The meter says 46K, but there isn't room on the dial for a sixth digit, so I think that it's probable that this 30 year old van has done 146K... So this brings a couple of questions to my mind:
1) I know that this sort of mileage on a diesel is usually nothing to worry about, but how do petrol engines fare?
2) If this high mileage spells bad news, should I avoid? Would a replacement with a recon be needed, or just certain components? Sorry, I'm not mechanically experienced, so I don't have a nose for what's likely to fail after that amount of mileage.
I had a bit of a drive in it, and nothing jumped out as worrisome (with my very limited experience). The current owner said that it doesn't tick-over so well, esp if warm, but looking at other threads it seems that the connectors to the starter-motor just need a bit of a clean.
Any help, advice, direction would be great.

Thanks,
Andy
P.S a history check says that it's only done 300 miles since 2009, if this is typical (big "if") usage over the vans life-span (check revealed 10 owners), then is it so infeasible to have 46K mileage? [Holding out a bit of hope...
