"Got 18,000 miles on my year old (bought June 2007) 2008 Impala LS 3.5L V6 with FLEX FUEL... consistently 26 MPG in town, and 32 MPG on the HWY. Roomy, reliable, comfortable, and QUIET running, XM radio, and SIX PASSENGERS. Huge trunk, and it looks good coming, going, and just parked in the driveway. The only expense other than GAS has been oil change and tire rotation from the Chevy dealership. Can't say enough good about this car."
