Garage called this morning,
Dealer was angry at me for not speaking to him first (as I originally spoke to the broker on Friday), he then said that I can't "just reject" the vehicle, and that the 14 day cooling off period doesn't apply to me, because I can't prove the fault was there. Also I can't just reject the vehicle without giving them a chance to fix it.
I explained to him that I'm not changing my mind under the 14 day cooling off period, I'm exercising a section 20 CRA right to reject due to it being faulty, and I don't need to give any opportunity to fix - I can just reject it outright and that's basically all there is to it.
He then replied "ok fine, let the finance company deal with it".
So I spoke to the broker this morning and their specialist returns/rejections guy, they're basically saying I'm 100% correct, as far as my rights go, they're going to handle the rejection themselves and they're also going to reimburse me for my hire-car costs.. They're saying it should be an open shut case..
Standard second hand car dealer having a tantrum when you're returning one of their faulty cars.
