Actually, according to consumer reports the Chevy Impala is one the best picks for a large sedan. I would agree with that because I bought my wife a new 2006 Chevy Impala LTZ that we still have. It has all the bells and whistles and has less than 60,000 miles on it right now. It's riding on Michelins and is very quiet. I drive a little Honda CRV and am always impressed with the quietness of the Impala when I drive it. The CRV sits on Michelins too, and is not noisy by any means, but the Impala is very quiet. One time when we first got the car, I was heading over to Palmdale and was driving the wife's car. She said, uh bubba do you realize you're doing a hundred miles an hours. I truthfully didn't. I'm not one to drive fast other than to try something out. It just handles and drives so well, the speed got away from me without knowing it. I immediately slowed down. I haven't pushed the car passed a hundred, I wonder if it doesn't have a cut off on it, because most cars will only run about 98 before they start warbling. I had a Mazda extra cab pickup one time with a super duper engine in it that would do 135, I know it didn't have a shut off. That was on a completely deserted good road, where a fellow in a new Chevy pickup lost a bet in the quarter mile, and top speed to a guy driving a "little tin can." I still maintain, I don't regularly speed because these incidences were very far apart.
