I saw that too Phil - but WTF? an unrestored 1953 Buick Roadmaster went for $1.5 mill (once owned by Howard Hughes, but so what?) - and a Shelby GT500E that wasn't even original (i.e. assembled from bits of other cars, so numbers didn't match) went for over $500,000.
Barrett Jackson appears to be a bit of an egotistical pissing contest to me - and run by a bunch of hucksters. Even the genuine articles (71 Hemi Challenger - $160,000 and a one-off 454 Chevelle at about the same money) were $60k more than they should have been. That said and like anything, a car is worth what the highest bidder is prepared to pay for it, I suppose - but in my humble, some folk clearly have more money than sense or taste.
