Facts are still facts whether you like them or not.
Proceed at your own risk. California wants every dollar they feel entitled to. If you register your car as a 1965 model, the registration fees are substantially less than the fees you would be charged if registered correctly. That is where the fraud aspect comes in.
The next potential problem comes when you try to insure the car. Are you going to try and insure it as a 1965 car? Now you are potentially opening yourself up to an insurance claim being denied because you misrepresented the year of the car and paid much lower premiums.
Why not just avoid all the potential downsides and register and insure the car properly.
Or gamble that you won’t get caught and enjoy the drive. At least you can make an informed decision.
