What is the best style to compare auto insurance quotes?

I am needing to find new sports car insurance, and I of course would like to shop around for the best traffic. Can anyone recommend a good site that will compile your information and give you multiple accurate quotes from different companies? I am leery to enter my information into a third get-together database, so confidentiality, professionalism and no spam is a must. Thank you!
Answers:
Geico is good and others too. For a true comparison use the binder from your current insurnace so that the quotes you get are for matching levels on insurance that you have. Make sure you grasp the coverage too.
Progressive gives you the rates of other insurance companies, dont you watch TV?
