2006 Pontiac Solstice a good car for me?(plz read)

I am 16 and I plan on getting a sports car that won't KILL me when it comes to Gas prices.(i know the solstice is not Honda MPG but it will do) I think the solstice may be good but i don't know. I found one that cost $13,000 a few days ago do yall think the price of the solstice will continue to drop to the point where I could find one for $11,000 by March of next year? and if so will the insurance (of i am under my parents name) cost more then $200 a month?(it has like 177 HP and is not that fast so...) (oh and um...I am paying for 1/2 the month cost of every thing and my parents are paying for the other so $200 car payments and $200 insurance would'nt be a problem)
