Clutch judder was there day of delivery told him via WhatsApp I paid bank transfer and listed it was to make a purchase no repairs elsewhere only
Air con garage agreed to have clutch fixed at my local garage but I think they won’t really pay for it to be done and I am
Stuck with the bill then
If you reported a fault with the clutch on the day of delivery, and you did so in writing (via whatsapp), then they
must repair it, consumer rights act has you covered here, as this happened in the first 30 days. (because you reported it on day 1, the clock stopped at that point, even though it's now months later)
It's really that simple (which is why they're offering to repair it, because they know they have to and the fault was present at the point of purchase)
My thoughts would be to accept the repair, and if you're still not happy - P/X the car and move on to cut your losses.
You
may have the right to reject here, because you notified them about the fault on the day of delivery, but in all honesty - for a juddering clutch, I wouldn't go that far - rejecting a car is a long difficult drawn out process and should be used as a last resort (so for example the car's engine blew up)
