I know when I went into my insurance company and had the 2nd car added, they didn't ask any information on the car other than the VIN. Their computer system put pretty much all the information in about the car that was used to determine the change to my insurance rate.
Hey, you want to lay the fate of the world on the kid's Camaro? That's cool.
I bought a car, turned out to be an alien robot. Who knew?
