It seems pretty clear that we are at a market apex for the turbo Buicks, particularly the GN and GNX. Those values cannot really be compared with other G Bodies at this point in time. If a thorough analysis was done, I suspect there would be several subsets that average higher than standard G Bodies in general, such as low-mileage original Monte Carlo SS or Hurst Olds.
I personally like the non-special edition looks. The white or two-tone T-Type is the Regal I would want over the all exactly alike all black GN and GNXs. I like the 442s and Hurst editions, but my Cutlass will not be rebadged a 442 or Hurst, it will be what it is, a 79 Calais, but with a better drivetrain than Uncle Sam and GM would allow for in 1979.
