2008 Chevrolet Impala LTZ 4dr Sedan (3.9L 6cyl 4A)
This is the second LTZ we've purchased and both have the same fuel mileage about 24 mpg highway not even close to the 28 mpg advertised and both cars have over 10,000 miles on them. the rest of the car is great, good design great stereo and it handles great. I wouldn't recommend this car with the 3.9L engine because of the poor mileage but would recommend the car with the 3.5L engine instead.
Great stereo, power seats, headlights,exterior design and dash layout
Better fuel economy with the 3.9 engine, get rid of the cylinder cutout, it doesn't work that well, it's more of a gimmick than something than something that provides real value.
