Much like 911 Carreras, 964's and 993's seem to be much harder to find in colors other than black, white, red or silver.

I would almost automatically say a unusual color should bring a premium - unless it is especially hideous to the casual observer. What color is it?

Especially coveted classic colors (like slate grey) or signal colors (conda/viper green, etc.) bring documented premiums (through past sales).

I accidentally ran across a low mile continental orange early 911SC ('78) the other day and was just shocked by the "presence" of the unusual color. SC's in general (especial '78/'79 cars) seem to have a wider array of colors over later Carreras.
