i just bought a 2009 chevrolet cobalt like in mid February cuz i needed a reliable car for college...now the dealership is calling me to buy the malibu LT2 i originally wanted, but i didnt pass the credit for that amount..now the dealership offers me some rebates and plus i got a letter saying i qualify for discount for a new chevy vehicle worth 1500 bucks...Should i trade in my 4 month car for a new chevrolet malibu?...(malibu is a little bigger and luxurious than the cobalt?
