Wow. Didn't know that... Our insurance companies, at least the ones I've dealt with, allow you to buy a car and give you a grace period to let them know you bought a new car. Whatever coverage is on your previous car is transferred to your new car for no longer than seven days. For the guys that may have insurance companies in the U.S. that have different insurance companies, I'm only talking about the ones I've dealt with (Erie Insurance, Allstate, StateFarm). So, for example, can you buy a car on the 6th and drive it off the lot on the 6th? Seems like that would take some time before the registration, taxes and insurance would come around.
