Newer car fund.

Hi my name is Dennis and my wife and I recently had our first child. Since then I have been wanting a newer vehicle than I can fit a car seat in since we already got a newer car for my wife. When I say newer I'm talking like a 2006 model since I currently drive an 1999 chrysler sebring 2 door. I'm looking to get a crew cab (four door) Chevy Colorado so I can transport my child and have a reliable vehicle for the winter. With $6000 I'll be able to get exactly what I'm looking for but I currently wont be able to raise that much money before winter.
