Stormy in Colorado off the I70 has a 1949 Nash tow truck for sale, that is mighty rare. I've never seen one restored that I can recall.

with only 26 thousand miles on it. He wants 18,500 dollars for it. Seems like a no brainer if you have the money to purchase it.

Nash did not want their cars towed by Ford or Chevy wreckers, so they made a small number of tow trucks just to sell to Nash dealerships.
