It has been quiet on the forum today so I thought I'd throw something interesting out there...at least interesting to me.
I currently live in the People's Republic of California and we have a heck of a lot of laws here. There is pretty much a law for everything you can think of. The laws regarding automobile registration, insurance and emissions are some of the most complex and restrictive in the nation. With this in mind, I started thinking since I plan to build a car, maybe there is an opportunity to benefit if I plan things out correctly.
A little background on the "state" of affairs here. From what I understand there are heavy restrictions on engine swaps here. The engine type must match the one that was associated to the VIN or you won't pass smog. 1975 and older vehicles are smog exempt. SB100 (manufactured vehicles) are also smog exempt but require fees, inspections and general jumping through hoops I am not real excited about.
So here is what I was thinking, what if I purchased a running pre-1976 vehicle and build my car around it? The liability insurance would be cheap, cheap registration, no smog and no inspections or extra fees.
Now to the problem, I want as little of a pre-1976 vehicle in my car as possible. I don't want the weight or the antiquated engineering or the rust or...or...or...So how much of the car do I have to use for my built car to be considered the same car as the pre-1976 car? Obviously, the frame/chassis seems like the reasonable part I would have to use. Do I have to use the whole thing? Can I use only the center of the frame? Do I have to use a certain percentage of the frame? Can I use only the part of the frame that has the VIN on it?
To be clear, I want this to be legal...technically...so the department of motor vehicles has nothing to say about it. So what part (and how much of that part) would be considered the car?
