I'd say the guy found about 3,568 mouse nests, too.
If all that crap were mine, I'd unload them on whatever suckers would show up with fistfulls of money to drag those dryrotted wrecks home.
Sure, they might be classics, but the REALITY is that they're a bunch of non-running, dryrotted junks with tanks full of bad gasoline, crumbling leather and rodent damage. Even in their BEST day off the factory floor a 10 year old 'Vette would eat them all for lunch.
I'm not sentimental about such nonsense. I'd sell 'em all, keep the money, and buy a used Viper or Vette or maybe Supra Turbo to flog.
