Clean car but I have to assume it began life as a Malibu. First link below is the Ebay auction and the second is a dealer ad with the $60k asking price.
With the popularity of '70 Chevelle convertibles, the seller just might get his price, but it's probably about $10-15k high anecdotally...from my own experience...given the underhood detailing, etc.
