As far I can tell this is not a valid reason to reject a car- whether cat s or not. Plus it’s over 30 days.

Sill has a dent in it and wants a full refund, what are wrong with these people!
If he missed it prior to sale then it’s his responsibility for not checking the car properly.
stinks of buyers remorse.
