I've been very happy with my Impala. I don't think you can get a smoother ride from a front wheel drive car. Its very spacious, love the interior and trunk room. Its sharp looking and fun to drive. I bought mine off a corporate lease return, it had 72k on it when I bought it at only 3 years old. It now has 90k on it and still runs, looks and drives like new. Only problem I had was had to replace a wheel speed sensor at around 88k ($400). No other problems. Has been very dependable. A very nice, roomy, family car.
I like everything about it. I really like the tire pressure monitoring system - it has saved me from ending up being stranded on the road somewhere with a flat/low tire!
This was the last year for this body style. I still like this body style, better than the new.
