Considered that a possibliity but we all know that 2 cars painted the same color the same day, 5 years down the road can look dramatically different depending on how they were used and how much sun they've seen. I learned this lesson in spades when I tried to do something similar a number of years ago. I tried to acquire a rear spoiler without painting it for a white Bonneville SSE that didn't come with one. I found perhaps 6 different white wrecked Bonnevilles (same paint code, there were actually 2 whites) that had spoilers in great shape. None were close to the factory paint of a 2 year old well maintained car that I owned. Ended up having it painted, even then if you knew what you were looking at you could see the difference. Never ceases to amaze me.
