I just had the 2002 rear upgrade done to my car.I am very happy with the look. However I am a little dissappointed in the color match. I have a 2001 spa yellow which is of course metallic.From certain angles the color is a match from others it is slightly off.(darker) Is this usual or should I freak out on the body shop.They had my roof to compare through the paint process to help for an exact match.Is there such a thing as an exact match for this color?
