If you want a quicker sale, YES.

Unless your car was actually built in 1965, it is NOT a 1965 car, and if it is registered as a 1965, it and you are in danger of being impounded/prosecuted as a fraudulant registration.

If you are the first owner, then you registered it incorrectly. If you bought it from another Ca. owner, then HE registered it incorrectly and they haven't caught YOU yet.

Now, there was an amnesty period where any "incorrectly" registered vehicle can correct the registration without penalty. But, I'm not sure if that program has expired.

If it was transferred from another State and was legally registered according to that State's registration laws, then California will recognize that registration as legitimate (until they decide not to).

I would get the sb100 and register the car as the year it was first completed. Makes the car much more saleable too.

Lots of threads on this topic. Do a search and be prepared to read and read.
