no - you nearly have to break them to get them out...very difficult according t my local bodyshop...i was going to have all mine colour coded (like the 135R)...but it turned out I would nearly have to buy a full set of new vents as they are very difficult to get out
Have a word with Simon @ Brooke Kensington. They have just had all the vents sprayed to match the car. Wanted to do the same to mine but £450 was too expensive!
