one Dodge dealership in Darien New York kept a 1969 Charger 500 with a hemi until 1989, and then finally sold it (with 1270 miles on it from parades and events) It's just been sold at BJ for 341K

Speedy Greco and his brother used it as an attraction for their dealership. They displayed the car in the showroom, took it on parades and special events. 

The following year, in 1971, the Greco brothers parted. Speedy's brother kept the dealership. 

Speedy left with a couple of new cars, one of them being this '69 Charger 500. However, the Charger 500 was never titled or fitted with license plates. 

He kept it until 1989, when he put it up for sale to raise capital for a state-of-the-art spray booth in his restoration shop.
