My car had the typical peeling on the steering wheel trim but that was quickly fixed with some 3M carbon vinyl.
Then I put on a carbon fiber boot spoiler which was a pain to glue on as it was cold outside and the carbon is quite stiff.
The 3M tape that came with the spoiler was useless so I used window glue and held it down with duct tape for a day to make sure it sticks.
While getting some new 225/45/17 Goodyear winter tyres fitted the shop also did a rear muffler delete with new twin tips.
