10 days before trading in my immaculate 2.7D PL for a 3.0D PL some ass has scratched the driver's side backdoor. It is about 8 inches long and about bike or shopping trolley high and deep enough to feel with my nail. Tried a wee wax but still obvious. From anyones experience how will the dealer deal with this, should I try to get it done before the trade?? What is it going to cost??? Any advice appreciated.
