I think it actually depends on the ghost. Like if you replace part of the car, it will still haunt it. But if you replace all the parts at once, the car will be significantly less haunted.
Similary, if you rebuild a building to be similar, but not quite same, the place is still haunted. But if you like build a mall, it would be significantly less haunted.
Does this mean if you die on a moving vehicle, your haunting spot keeps on moving in whatever direction?

AKA buying a new one?
Only if you junk the old one in the same place. /s
