Car question.

Car question.

I bought an '07 Pontiac G5 GT (used, not new) last year and it's been a great car. I was, however, bringing home quite a bit more money when I got the car than I am now. I'm still making all of my payments on time, but it's getting tighter and tighter. Additionally, because I'm making payments on the car, my insurance is higher because I'm required to have more coverage. I'm sort of unsure how to phrase my question, but I'm trying to figure out if there's a way I can trade the car I have in for an older car that I wouldn't need to make payments on? Am I stuck with this car until I pay off the entirety of the loan? And as much as I'd love to not have a car, I have a long commute to school that requires it. I'm completely clueless about all of this, so any and all information is super appreciated :]
