I suppose at the moment it's just a dream, but what's the viability of something like a sixth gen Riviera or Oldsmobile 98 turbo V6? Or some other lesser known car that came with a Buick V6 from the factory? Regals are really cool, but the something out of the ordinary has always been more interesting to me. That's not to say turbo Regals are ordinary compared to a Ford or Chevy though.
