Mileage wouldnt bother me on most things.When we used to have a garage and car sale pitch some of them had done that in 12 months Its strange as some cars ie under 20,000 or older with 40,000 can be problematic but star shipers can be trouble free.I think the highest my mum had was a old 740 volvo with 220,00 and it was sweet as a nut.My last car was a lwb shogun 122,000 pulled like a train and mechanicaly sound.The body let it down though.I remember buying an old Jetta one family owned and about 40k.Everything broke !! starter,alt,head gasket exhaust.Short journeys and standing about are now good imo.
