Howard Hughes' 1954 Chrysler New Yorker is for sale, with his name on the title.
1500 original miles.
You'll need a roof rack. The trunk is full of an air filtration system designed and custom-built by Chrysler (at Hughes' insistence). The air system cost several times more than the price of the car.
You may have seen this one (as I did) at the Imperial Palace car collection in Vegas.
The price? Yours for only $125,000. They'll probably negotiate.
