Leave it as it is mate, all those small imperfections all have a story to tell, small cig burn in the passenger door card, steering wheel with tape around it, my mate telling me the other day about it when i showed him the pictures. Even the RS bade on the wing is his idea and the number plate is also from when he had it made!
It's amazing the stories about it, nothing bad in any way.

You could tell in his voice he wished he never sold it, he was amazed it was still the same as when he sold it.
