I just recently dropped my car off at the dealers I was buying my car from, just told them that would be where was best for me. Got my cheques a few day later. 1 for gcb one for pro rata of the ap paid.
I handed mein back a year early, but pretty much is the same process as at the end of the lease.
I am still waiting for the letter of exemption for the road tax from dwp, my v5 has arrived even the letter to say I am no longer the registered keeper of the scheme car has arrived.. So had to tax the car hopefully it comesbefore the end of the month then I can put it on the new car and only lose 1 months road tax.
