The Impala is a very good value because it includes features of cars costing a lot more money. The features include: power heated leather seats, steering wheel mounted audio controls, XM Radio, On-Star directions, tire pressure monitor and Dual-Zone climate controls. It has a comfortable ride, handles well and gets excellent gas mileage for a car of its size and weight. The 3.5L motor has enough horsepower and runs on regular gas. It has a very well designed interior with comfortable seats and nicely designed controls. The braking performance is good. Prior to buying my Impala, I have rented both the 3.9L LTZ and 3.5L LT models. I choose the 3.5L engine because of fuel economy.
Interior design which includes: Dual- Zone climate controls, leather heated seats, OnStar directions, XM radio with an auxiliary input jack for an iPod.
The interior includes hard plastics which may appear to be lower quality. Note that other car manufactures are also using hard plastics in the interior.
