auto insurance in brooklyn

I am curious to get a range what others in Brooklyn are paying?

I turn 29 next month, I only got my license last fall(I guess I was spoiled living out here by mass transit).
I am getting a used car(will be my first) as a gift(97 buick lesabre).

I went to the geico/esurance sites to get a basic quote to have a general idea
of what I should pay. It seemed way off, almost $500 a month(both).
It seems high even for Brooklyn. I am wondering the reasons, I am almost 30 but a new driver. I have a good career, but bad credit.. etc..
not sure other reasons that make the cost go up...

thanks for any feedback...
