To hell with correctness......get a Data tags, tag and have some fun, make your own "numbers" up. I spent some time making up my own car with it's options, 540ci, 5-Speed, special order everything, etc, just put down what I'l building, love it. Just an idea is all. I do have the original tag but that's not going anywhere other than in a zip lock bag in one of the cars several folders for safe keeping.
