Are 72 Olds W30s that valuable??

[DW31S]

I'm a freak for white interiors and that color combo. is breathtaking. Unless I missed something (which is entirely possible), I don't see the paint name/color/code mentioned or a picture of data plate. Believe it or not, there are some savvy NHRA Stocker guys running that drivetrain because of the factored horsepower. One can still make decent horsepower in spite of the lowered 1972 spec compression. I'd think if that car is truly what the seller is claiming, that authentication should be fairly easy. And price? Well, it just might be the only blue/white 11k mile specimen out there; I've seen less sell for more.
