Something sounds decidedly strange here.

You say the car is new so the warranty would be via Volvo UK & any dealer would recoup the costs of repair from them.

What was the nature of the failure, only reason I could see Volvo UK washing their hands of any responsibility would be in the event of a major failure that's been caused by either a customer issue or supplying dealer negligence.

If you purchase a car from Car-Wow or the like the dealer could be anywhere in the country & you'd not be expected to return it to the supplying dealer for work under warranty.
