@kezo surely the dealership should cover the cost of the de-registration?
my mistake, quoted the “registration” fee of £55 and as such edited my post to save confusion, however a new registration fee would still apply.
As in my previous post, there’s more to this, with the dealer insisting on payment by Friday, suggesting they want the car to apply to Feb targets. Registration aside even on a 74plate could still be collected next week if the op was busy but, as it happens confusion also comes into play as the op wants a 25plate.
