This is something that I feel many UK owners will be concerned about, as the cars have been around long enough to pick up stone chips etc.
I too found that the dealers dont have any touch up paint, mine said they never had any from day one, but reckon touch up kits are on the shelf in the USA. Halfords say they can do a match from the colour code no probs, but Ive not tried them.
The best advice on this subject would come from the "Bodyman"
