I suppose the answer will vary , depending on who you ask. The Jetstar 1 was not typically considered a muscle car by the motor press, and was not marketed as one by Oldsmobile. It was a Starfire without the Starfire price, and minus some of the flashy and luxury items the Starfire possessed. It was, then, a chance to buy the 345 hp. horsepower 394 CID Starfire engine in a full sized car at a bargain price. Oldsmobile's first entry into the muscle car wars was the F-85 of 1964, with the 442 option . The central idea of a muscle car was to put a large engine into a lighter weight, mid sized car . While I agree that the Jetstar 1 and other full sized Oldsmobiles with the 345 hp. engine were lively performers and fine automobiles, I don't think they fall into the muscle car class. I own a 1962 Starfire, and even though Olds marketed it as a something of a "sports car", it was, in fact, a luxury performance car , similar to the Pontiac Grand Prix . I think your Jetstar 1 may fall into the luxury performance category as well.
