Dealers and manufacturers are only issued one plate. I haven't had a front plate or a registration sticker in years.Think he meant the Vett wasn't from Texas since it didn't have the required front plates.
However, that's probably not true either. A lot of Texas Vett owners don't put a tag on the front since their perception is that it messes up the visual aesthetics. (And I guess, they're willing to pay for that decision if required to do so).
It'd be interesting to know what percentage of Corvettes don't have front tags in Texas.
