Maniac said:Perhaps post a picture and we'll be better able to advise. My car is a 2009 and I've got some wear on the bolster where I enter and exit. Common on all cars not just Z4's. I have a paint kit that I use now and then which I water down and rub over any areas of wear to make it look brand new again. I have 24000 miles on the car, but more importantly its used every day and is over 4 years old now but the seats look almost new.
Maniac, can I ask what kit you have, and where you can buy it from? I have the same extended pure white nappa interior as yours and am experiencing some wear on my drivers seat side bolster, would be good to touch it up.
thanks
