Well, All the cars u mentioned above, TL looks best and most powerful, but since money is an issue, i think you should go for Camery, maybe later days when u have more money u can buy a sport car.

GSR just too small for a family car. It is a Kid's luxury car. I will definitely get rid of it when i get marry.

As for how much u can get, i think around 10k, maybe little less.
