That must be a US specific thing, because that sounds demented.

It is untrue in the US. Manufacturer warranty follows the car. And it does so automatically, it is tied to the VIN and not whoever has the title.

		Eh, its kind of mixed. Some manufacturers like Hyundai have essentially a baked in extended warranty (10y 100,000mi) that is non-transferrable, only the base warranty (5y 60,000mi) gets transferred.
