Our hunt through eBay's automotive treasure trove for rare 1950's cars continues with this 1953 Muntz Jet. Created by Earl Muntz, entrepreuer extraordinaire who earned his fortune plying consumer electronics and used cars. But selling yesterday's iron wasn't enough for the "Madman," so he embarked on creating his dream car-- a process that resulted in the vehicle shown here. Not a one-off 'special' like the other cars we've seen recently, the Jet was actually a serialized production car, though less than 400 units are thought to have been manufactured between 1952 and 1953.

Unusually, all Muntz Jets are in fact removable hardtop convertibles. Designed by Frank Kurtis of Indianapolis and dirt oval motorsports fame, the Jet made use of both Lincoln and Cadillac V8 drivetrains, depending on when the model was built. This particular example is powered by the former, and has been restored in plum metallic and white leather.

Estimated to be perhaps one of 50 surviving Jets, this rare bird has been bid to more than $58,000 as this is written, but has yet to crack its reserve.
