General-Auto-Insurance.com – Insurance For Cars
This site will let you look up auto insurance quotes, and a distinction is made between car used for personal purposes and commercial auto insurance. That difference is set down at the very start of the search process, when you are also asked to input your ZIP code.
That makes this site a little different from others in which you are asked that very same question at a later stage, much to your dismay as you might have filled in a form that was not compatible with what you were looking for.
Other than that, the site includes a series of interesting articles such as “Should I Buy Auto Insurance Online or Go Through an Agent? and “What Is Non-Standard Auto Insurance?”. If you have a minute, give them a glance.
