If you never drove a Honda Accord, Mazda 6, Camry, or Nissan Altima, the Impala might seem like a great car. However, having driven this car for a few months now, I find it excels in only one area -- gas mileage. I get about 28 mpg average, which is great for a large 6 cyl car. Everything else about the Impala seems crude & under- developed. It's already been in the shop twice for a faulty steering part & brake rotor resurfacing (at 15,000 miles). Acceleration is rough & uneven, handling is awful, and seats are poorly designed. This is not the car that will save GM from bankruptcy.
Gas mileage, exterior styling.
Handles like a car from the 1970's -- wallows in turns & discourages all sporty driving. Seats need lateral support & better back support. Engine/trans computer mapping is way off & needs re-design.
