I purchased a 2017 MY XF which was a demo model. After purchase I noticed that some of the interior trim around the doors and footwells seem to have serious marks which I cannot remove (I assumed at the time that they would be easy to clean off and the dealer just did not care or bother to remove them). The car had around 3,600 miles on it, but whoever used it was either extremely careless or the interior plastics are of very poor quality.

Does anyone have any guidance about how to remove these marks? I have used interior plastic restoration products and the so called 'magic erasers' but they do not work. It looks to me like the quality of the plastics inside my car are very poor quality and, if I want a pristine finish, I have to replace them or is there something I could do?

If this is how a very low mileage car looks, I am certainly not confident that this car will last the length of time I wanted to keep it and I should probably just accept the losses and sell it now.

Anyone out there have any thoughts.
