Please help me chose a car.?

The rest I really don't care for. Pontiac Grand Prix is too big and bulky in my opinion. Dodge Charger has too many miles for the price. Unless you can negotiate a much lower price, I wouldn't bother. Chevy Camaro is nice but I would be concerned about reliability. These cars are generally driven hard and may exhibit problems.
Regardless on what you decide, make sure to check the carfax report and have the car inspected by a certified car mechanic.
