This car has been rock solid since I have had it. I bought it and it felt new, and it still feels just like new. It has adequate acceleration, and yields respectable fuel economy, though not quite on par with other V6's in its class. I average about 25 mpg, and I drive fairly conservative with almost all being highway miles. The interior feels much more expensive than what you pay for. I test drove a 2009 Malibu before I bought this, and that interior was extremely cheap feeling in comparison; it was the LT1 trim so that could be why. Seats are very comfortable and you can easily drive long distances without feeling like you rear is going to break off.
I really enjoy the Sync system, since it is annoying to be holding onto a phone especially in traffic.
My only real complaint is the horrible handling in winter. I came from an AWD Subaru, so maybe I was babied, but this is seriously scary sometimes. I have never known a FWD car to fishtail on slippery surfaces as much as this car does (I've heard it has to do with the suspension). Also, it really struggles to get going too when there is a tiny amount of snow/slush on the roads, and I have new tires on. I really like this car, but I wouldn't get the FWD model again, especially since I live in an inclimate weather area.
No, it's not driver error either, since I have lived in snowy weather areas my entire life, and have gone through many other vehicles: 4x4, RWD, FWD, and AWD; this car just feels that unstable to me. I will be getting rid of it by next winter solely for this reason.
