Car Insurance Basics

Car insurance is one of those strange purchases: Everyone needs it, but no one ever hopes to have to use it.

But because you’re required by law to have it, and because it will offer you much needed financial protection in case you’re in an accident, you might as well buy insurance from the insurers rated the highest in overall customer satisfaction, right?
