Fashions change. Both colors and shapes of body shapes change to indicate "new car". Silver was most popular in 2005. I wouldn't risk buying one of the current fab colors - swamp-green, cow-poop brown - since they might be ridiculed in 15 years as was TV Al Bundy's "Gold Duster". The only bright Mopar color of the early 70's which people appreciate today is the "Plum Crazy" (purple) Challenger. Similarly, every decade car bodies would change from round to square. The current "cross-over SUV" car/minivan look won't last. Jaguar just came out with one, perhaps a bit late to the party.

Re painting, I will use a solid-color, single paint. Clear coats decay to look terrible, as seen in every parking lot in sunny states. Also hard to repair damage to a clear-coat. Metallics are tricky to lay down and match and the metal particles oxidize over time.
