Thankfully the guy that did it is paying for it. Not so thankfully is the cost - I rang Seat yesterday and they quoted me just over £300
I know it's partly my fault for letting him smoke, and to be honest when I first had the car I had a total ban on eating/drinking/smoking etc but I spend a massive amount of time in the car (12.5k in 2 months from new
) and it's hard to keep such a policy going.
I think I might just buy the cover and try doing it myself, or get one of the people mentioned above to do it.
