I think owning a more "vintage" car requires more care and is less likely to be mistreated by the owner, if you look at the MOT history database on some newer vehicles when the car has its first MOT it fails on pure neglect items such as bald tyres, wiper blades fraying, worn brakes, no screen wash fluid. When someone decides to take on a vintage car it almost certainly means ongoing work is required to keep it ticking over and its more likely to be bought by an enthusiast rather than someone who wants to go from A to B
