Hi I am in the market for a new car but don't know much about cars. I have looked at a few cars and want something like a VW Golf (old shape) or a Vauxhall Astra (2004 onwards) and I want a diesel only. I've been told that the VW diesel engines with high mileages will run forever but I'm not so sure so would like clarification please.
I have seen a few on Autotrader, in particular the Vauxhall Astra - a couple of models that are going for quite cheap (around the £3k mark) compared to the rest but they both have about 105k mileage with full service history. Would that be too high? One is an ex cop car that's been owned from new so it's probably been thrashed and the other seems well taken care of. What else do I need to look out for?
Any help would be appreciated, thanks.
