Rob said " but I was told by a dealer that now that it has passed 50,000 miles it might be more difficult to sell" and the dealer is undoubtedly right. You can rationalise the "better with use" arguments all you like but the reality is that two cars side by side at the same price and spec, the lower mileage one will sell first. If you believe, as some seem to do on here, that cars dont wear with mileage then you can get yourself a bargain by buying a high mileage one cheap.
What mileage will engines do? Depends on the engine and its design. When I firsty started in the early 60s it was normal to have a decoke and head off at 30k miles and small engines were done at 60k. Even now a big lazy will outlast a high rev smaller unit, but you can expect toi see wear at 100k.
But then a car isnt just an engine. Bearings wear with miles. The seat upholstery wears with hours. The paint oxidises. All sorts of bits and bobs wear with age and mileage and many of them arent cheap to repair.
Spare parts? Depends a bit on country of origin - its far easier to get spares for old Brit bikes than Jap ones for example. But in 30 years of classic car ownership the bits I found went obsolete first were things like plastic lens covers, chrome trim, door handles. Nowadays you might well start to get issues with electronics and sensors and things like the abs pumps.
Door handles???? We don't all have those to worry about!
