Cobalt LS 4dr with no options. With almost 4 months and 5000 miles, I think this is going to be great commuter car. 31-34 mpg mostly highway commute to work. Great AC and adequate radio/CD/mp3. Comfortable front seats and adequate rear seat room. Big trunk. Added aftermarket cruise (really just expensive switch), factory servo controls are already there. Plastic wheel covers and small tires will be replaced with alloy wheels and bigger tires when appropriate.
Price, space, gas mileage.
Better interior knobs. The window crank knob actually had molding sprues that hurt fingers. The shifter could be little smoother. Rear disk brakes and alloy wheels on base model would be great.
