I had this issue with Carmax. As long as the vehicle is registered to you, you can trade it in without having a copy of your registration. Carmax has access to DMV records and they can verify who owns the vehicle. I'm speaking for California transactions. Not sure about out of state.
Yes, as long as you have the title or transfer of ownership registration.
Yes, some companies will insure your car without registration.
The answer is no.
All car dealers SHOULD keep registration fees on a trade in car but if a client requests other wise then there is not much they can or will do, although if you ask to know the registration fees they should be able to tell you.
No. But the dealer has, or can get you, a temporary registration.
No, because you can't show legal title to owning the car.
In most states, you can trade in the vehicle without it being registered. However, you do need a TITLE to prove that you own the vehicle.
In all states, operating a vehicle without a valid registration is a violation of some sort. In some towns, if you get pulled over without a valid registration, they can hook your car. (My daughter can verify that!) If the car was, in fact, registered but you didn't have the documentation with you, that is a lesser violation (failure to produce documentation).
If you have a bill of sale there is a bond you can pay for in Georgia that allow you to register the car.
Yes, it is illegal. You will be cited and your car will be impounded.
No, there is no such thing an an "insurance card" in Massachusetts. The insurance information is on the registration, you can't get the registration without it.
Should not cost you a cent. Simply show them your paper-work for your vehicle such as registration, [insurance], and also your driver's license and they'll appraise your car. This process however can take awhile.
