I purchased a 2006 Impala in 2007. I was originally drawn to its style, power, comfort, very quiet ride, etc. I got a good price for it because it was a former rental. I bought it with 28,000 miles and traded it in at 99,600. In between that time it was pretty reliable. Right after the warranty ran out, I had problems with the steering system popping.I began to notice other problems at 75,000. The paint had the durability of nail polish. The driver's side visor hung down. I never could get the brakes to stop pulsating despite changing rotors. Random warning lights came on. Finally - no heat at idle. Head gaskets. Dealer wanted $1,900 to fix.
Very smooth, quiet ride. Big and comfortable. I usually averaged 25 mpg city/highway combo.
