One of the great things about using Compare.com is that you enter your driver and vehicle information just once. From there, auto insurance companies look at the same set of information in order to offer their best policy quote. Because the driver and vehicle assumptions are the same across all potential policies, drivers can be absolutely certain that they are reviewing comparable quotes.
It is also worth noting that none of the insurance companies on Compare.com receive preferential treatment – the quotes an individual receives are real prices. Results are listed from the least to most expensive premiums.
