I have to second the 1970 Buick GSX Stage 1...little known fact about the White 1970 GSX cars- Apollo White was the same code as Glacier White.
But to up the ante...the
1970 Buick GSX Stage 1 Buick Showcar gets my vote. 100% street legal, licensed car, this is the one of none produced show car, in Pearl White with one-off show circuit parts and interior.
