Advice always welcome and yes i am looking for something to use on the tailpipes, but judging by the number of cars on the forecourt with the same issue it seems maybe the finish is not up to the mixed climate of the UK....

Can't speak for myself but there are a number of us on here with the saggy seats, i noticed mine only weeks after getting the car, the passenger seat sagged after carrying a few people on 100 mile plus trips, since not being used so much it seems to have returned to normal shape.

Sadly the drivers seat is well an turuly saggy with 10k miles on the clock.
