What would my Car insurance Rate?

[Flyboy92]

I am looking at getting a new car and the two choices I have for a car are a 2007 Mustang GT Convertible or a 2004 Mustang Cobra. What do you think my monthly payments would be on each one of these vehicles? I am 18 and i was in an accident last year and my rates did go up so what do you think it would be I have state farm and so does everyone else in my family so our rates are low and we've had them for over 25 years I pay right now on a 2002 cougar V6 full coverage for $150 a month so what do you think my rates would be on a new one I am also still under my moms insurance. Thanks for your help
