Regarding fine art . . . it's not a good comparison. Art is universal. Musclecars are cultural.

Art can be used for a comparison in this case as a comparison of "collector thinking".
Any thing valued on pure rarity and not on beauty alone could be compared this way.
Heck, not all expensive art is nice to look at, and some that are, aren't necessarily more valuable than the ugly art.
When the comparison is done from a "car guys" point of view, the value for the 4 door does not stack up,but,from a "collector's perspective" it certainly can and does.
I think that is kind of what Riggs was going for in his comments.
