Doris Day '69 Ragtop

Its also quite possible that Chrysler Corp. retained ownership during the time the car was used for the show. It may have merely been loaned to the studio for promotional consideration (vehicles provided by Chrysler Corporation appears in the closing credits of many television shows of that era). When it was replaced with a 70 Barracuda the following season, the 69 would have been sold off to it's first actual owner who may have never known the history of the car.
It would also have been more likely that the car would have been leased by the studio rather than the studio itself owning and then selling the car within a year.
I've seen those credits and was wondering the same. Was directed through the Doris Day Club facebook page to a Hemmings article on 72 Charger with a similar TV history. Checking into Glendale Dodge, who prepped the cars used, and Herman Hadler PR, who handles Chrysler's product placement in TV and movies. Also made contact with Chrysler and with Hamtramck historical club. Progress...maybe
