In places like Massachusetts, some cars that are "mostly vintage" get titles as year of build. They have to follow the rules for the engine / trans combo year. I believe California is the same. ( Guess where Mass got their rule book?) so it isn't always easy to say generally or in a broad sweeping statement that it will always be the case.

As Seth was saying about the modifying of the tractors, that the EPA and most states are becoming very heavy handed and very particular about messing with these systems. And here in Mass, we are voting once again to force the big 3 automakers to provide service information to businesses and consumers so we can fix our cars. I think this is the third time we've fought over this. Thanks to Cat and John Deere, they believe they "own the technology" and while you paid thousands upon thousands of dollars.. you only get to use their technology... you can never own it. As long as the EPA wants to enforce these emission laws that is! And Seth's story drives home the point. The OEM gets held to a standard or face penalties ( huge ones too!) but some "guy" / "shop" / "company" modifies something for what he sees is a benefit for him.... but the law thinks otherwise. And we've been doing this for decades. I think the end is closer than we've realized for awhile now. It'll be like it was in the mid 70's - color changes and graphics, body kits..
