The best paint job I ever saw was the Lincoln Marque X (concept for the Lincoln Mark VIII's of the 90's) and it was a tangerine pearl.....it looked liquid and that you could reach inside it.....so I gotta agree, the matte paint finishes don't do anything for me either.
I don't think a tangerine pearl Viper would be good either, but if you're looking for ideas consider taking a standard color and adding a tinted pearl to it....for example:
-silver with a blue pearl
-red with a burgundy pearl
etc.
