Could I buy an auto insurance without a car?

Could I buy an auto insurance without a car? I have no car yet and I plan to buy a used car from owner. So I would like to rent a car for a week to find a used car. Before I buy my used car, could I buy the auto insurance first? Thanks!

you can get a insurance policy from some insurance companies. it is a non owner insurance policy. it should cover you in any vehicle that is borrowed or rented. the insurance company we have told us we could do this but it cost more than having a car on the policy. you should call an insurance company and ask them about it.
