<human>: Can you condense the text into three sentences or less?

My daily commute to school is probably about a 70 mile round trip, and my current car (it has 45,000 miles on it) just was not cutting it so I started looking for something smaller and more fuel efficient.  I had my eyes set on a Chevrolet Cruze, but once I found one and started negotiating with the dealer they instantly tried to take advantage of the fact that I have never purchased a car solo before.  So in total they were going to charge me $13,700 and they were going to give me $2500 for my current car (they low balled the hell out of me and refused to budge) and the monthly payment was going to be about $200 for 75 months.  This is where I really started to feel the need to back out of the deal.  After yesterday was the day I finally backed out after I asked them if we could save me around $500 by not doing all of the dumb stuff that these dealerships do when they take a car in to be able to charge more.  I work at my school under one of the federal work study programs, and i make around $400 a month so I would have been able to afford the car.
<bot>: Backed out of purchasing a vehicle that would've required me to take out a loan on top of my student loans.  Did I make the right choice?
