Insurance companies tend to lock up when presented with older serial numbers, even those that are US cars.

Anything prior to 1980 (I think) when the standardized format was introduced, wacks out the computer.

I remember my father trying to insure a 77 6.9 10 years ago. We had a complete paper trail on the car, and it showed it being delivered new in Baltimore, Md. BUT, because it did not have the expected sequence, the insurance co. declared that it MUST be a grey market car......

I've registered a few grey market cars with my insurance company over the years, and all they care about is the DOT and EPA release paperwork.
