This has been a great car with excellent fuel economy. It has the 3.4 V6. I get about 32 MPG on the highway which is very good for a full sized car. Its the leader in its class for fuel economy. It gives you a very comfortable, quiet, smooth ride. This car has never been back to the shop for anything other then oil changes. I would highly recommend this vehicle. I have talked to others that have owned Impalas and they have all had nothing but praise for the vehicle. It was priced much cheaper than the Toyota Camry and the Honda Accord and I felt a much better value after I did my comparison test drives. All I can say is don't sell yourself short by not trying one. Its been a great car.
