Technically, every car is a one-year-only car. A '53 Ford is the only year a '53 Ford was sold as a '53 Ford, for example. The year before, they were '52 Fords. The year after, they were '54 Fords.
I'm not trying to be a dick, though I'm pretty sure I'm sounding like one at this point, but the whole "one year only" thing has always bugged me. Like I said, I can't think of anything else besides the Tucker. It was sold as a model year 1948 vehicle. None before 1948, and none after 1948.
Wasn’t the superbird a one year car?
