The paintwork on my Royal Ivory 2001 +8 was so good when I bought it that I invested in the protection film at the time of purchase. The only time that you can see it - and on close inspection at that - is after a wet and dirty run when an almost invisible amount of dirt can be detected on the upper horizontal edges. Personally, I think that it was a wise investment judging by the amount of dirt that acrues on the surfaces it is applied to, particularly over the winter months. I understand that most upper end performance cars now come with this as standard but I stand to be corrected.
