CLEAN CARFAX , LOADED , and Substantially redesigned four years before, this Impala LT received a cleaner, more sophisticated exterior, a badly needed interior upgrade, a Flex-Fuel 211hp 3.5L V6 that gave the LT an additional 31hp over the previous generation base engine, plus great features like dual-zone A/C, anti-lock brakes, traction-control, etc...even a remote starter! J.D. Power and Associates gave the 2010 Impala 4.5 out of 5 Power Circles for Overall Initial Quality Mechanical.
