Are there any 2014.5 Toyota Camry's?

I learned and do know that there was a Ford Mustang which was a thing in the past for years with a or.5. Are there any cars labeled as 2014.5's?

That's the difference bewtween *model* years and *production* years. Sometimes changes are made mid production. For enthusiast back then, that could very well denote a performance package not avail at the start of production. But auto parts suppliers in some/many instances, still need to know the *production* date. Especially those late or early in the production year. As some model changes do occur after or b4 the model change.
in the literal sense, one could look up the VIN number and tell what month the vehicle came off the assembly line. Coded in that VIN, one might find options that were not on other platforms in the same *model* year.
