Yes, it's called a Named Non Owner Policy.
No. You cannot insure a vehicle that you do not own. The exception would be in a family situation where two spouses own two vehicles and insure them on one policy.
Of course not
No. You can't insure a vehicle that you do not own. You must have an insurable interest in a vehicle in order to insure it.
Yes you can have liability coverage to insure you while driving an auto you do not own.
None, because the car has to registration have to be in your name.
You will insure the cars based on where they are driven the most. If you drive more in one state, insure the car there.
No. You can only get car insurance if their is actual a vehicle to insure.
You must have a financial (insurable) interest in a car in order to insure it. It works the same way with home insurance. You must own the home in order to insure it. Thus, whoever owns the car and has the title is the only person who can insure it.
You CAN register a car owned by someone else in some states, but doing so can lead to many problems if the driver gets into trouble and you are registered to the car. Insuring a car you do not own can also lead to problems but many more people do it. (e.g., if your dad is lending you his car and he says that you have to insure it.)
Any car that you can own that you only carry liability insurance on.
YES - registration and insurance are separate from ownership.
You have to own a vehicle to insure it then you have to register it as the registered owner. So if you are borrowing a vehicle either the owner has to insure it or you have to buy it from them
