Some of the Chevy dealers around this area are selling the Impala for less than the Malibu, all incentives considered the price, the car, and consumer perceptions. To me it's a small wonder that the Impala isn't selling better. It's priced way less than any of the ricer brands...
Then again, entry level Escapes are selling for less the $18K around here. Small wonder they are in the top ten also.
