Great little car. Owned for 4 months now and put 3000 miles on it. Got 25mpg in winter and now with 50 degree spring weather im up to 29.9mph according to the digital read out. The 2.2L engine gives it plenty of get up and go. Purchased the base model 2 door, with only power locks and keyless entry. Good buy for under $14,000. No mechical problems so far except a computer upgrade that was needed for the crankshaft sensor.
Digital readout: trip, coolant, mileage, oil life, avg speed and MPG. The back end of the 2 door coupe cobalts really suckered me into buying it. I love how the rear of the car looks more than any other car.
Need better OEM tires. Had my stock ones replaced. Were an accident waiting to happen in winter. If your going to be driving in winter were you received snow accumulations of a foot or more just overnight I recommend a different car. There just isn't enough ground clearence.
