1968 Cadillac DeVille Convertible- $35k
An ocean liner on wheels complete with two full sized leather sofas. First class all the way. Speaking of ocean liners it likely has a roughly comparable fuel economy and turning radius. But it’s 5,000 lbs of good old fashioned American steel from the glory days of American cars... and it’s a Cadillac.

That’s an outrageous price for a Michigan Cadillac. I suppose all the rust has been “repaired”.
You can buy a 1970 El Dorado with 500 CID...it’s full life in California for about $20k.
One of my friends had a Dodge Polaris back in the 70s. We called it the Queen Mary,it was so damned hard to dock.
