2011 Chevrolet Malibu LT1 4dr Sedan (2.4L 4cyl 6A)
Love. This. Car. We had an '05 and traded up this year (2012) for a '11. We got the baseline model for a really good price and then added a few features at Bestbuy for much cheaper than the dealer could do. I haven't had any problems with the gas mileage (getting about 28 combined). The only aspect that I'm not a fan of is the top of the dashboard. When the sun is directly overhead or in front of you, the reflection of the dashboard shines back into the windshield. It's can be distracting. Should have test driven during the evening... I've gotten used to it, but it can be a problem when you first get the car. The trunk is very deep, another plus.
Gas mileage, Audio, Comfortable Seats, Trunk is huge! Very quiet ride.
Some of the computers and electronics are "too smart." Keep it up-to-date but don't try and make it so smart.
