take some advice from someone thats been in ur shoes b4. you DONT want to put urself deeper in debt then you already are esp. b/c u got a quick love for a car.  It be dif. if the car you got now is paid off and ur making money on it if u sold it but  
a) you owe 52 monthes on it 
b) ur 5k upside down 
c) you will be going into 2 more yrs of debt on top of what you're in now if you trade it in 
d)  ur throwing money away in the end.   
Just stick w/ ur car now man, its a nice one.  pay it off and then look at others and keep that as ur daily   
OR   
sell  youre car outright, save money for a year or 2, buy car you want w/ cash and have no payments
