There are two kinds of vintage car registration in Texas (I hope I get this right because I'm doing it from memory). One is Antique and the other is classic. Both allow vintage plates, but the classic still requires state inspection and you are unlimited on use. Antique does not require an inspection and is for five years. You are limited to parades, driving to car shows, but is not to be used for regular transportation. You are given a little metal tag that you attach to the rear plate. You are not required to run a front plate, but when you register the vintage paltes you must have two. Hope this helps. See the ladies at the courthouse...they'll give you all the correct paperwork.
