well they need most of that information for the quote... insurance depends on more than just age and type of car you drive. it differs by location, driving record, sometimes the grades you have in school, and lots of other things. so, no site can give you an accurate quote with just your birthday and type of car.
expect to pay A LOT for that car at your age. i couldn't give you a quote, because, I don't know enough about you.
The best site for quotes would be the individual companies websites... like www.geico.com
some say they give you quotes from other companies to compare rates... but, in my experience, those quotes were really off compared to the quote the other companies actually gave me. so, take those comparisons with a grain of salt.
another good option would be to open your yellow pages and look up car insurance. call the companies listed there, some may not have webpages. they will also be able to give you a more accurate quote and help you decide on coverage if you don't know what all that stuff means.
