Bought as a family car. Lots of room and great trunk. The 3.8L V6 was well proven and it has been great (skip the 3.4L). I got the fully loaded sport package then upgraded it with police alternator, SLP rocker arms, SLP dual exhaust, K&N intake, slotted brake rotors & performance pads, and tuned ECM (LSX model). Have been a fanatic about maintenance & fluid changes (synthetic lubricants everywhere). No trouble except for clogged cat at 70K. At 100K it still runs and looks like new. Plan to keep it to 150K miles.
Power, visibility, ride. Easy to self maintain.
Wish GM left this car alone. The 2006- later years front end looks like the old ugly Lumina.
I bought this used - 1 owner before me. Drove great at first - loved the car - then this year everything just crapped the bed at once. The transmission went. I love Chevy but I will never own another impala again, my cavalier was more reliable than this car.
Heated leather seats and sunroof
better motor & transmission and traction control system
I bought my 2003 Impala Ls on February 12, 2009. Car had 70,000 miles.The car ran great for a long time until it was in a accident in july 09.Cracked my intake,cat converter.Trunk light kept killing the battery(no biggie). After the wreck and shop time I have not any other issues. Tranny is strong smooth, love the car. The car now has 102,000 miles... Already 32,000 miles in less than a year. It's honestly a great car. Other complaints also depend on how hard you are on your car. Hope this helps.
So far I love this car. I had purchased a 2005 Chevy Malibu Classic in July but wasn't satisfied with the feel of the engine so I traded it in for a car I was more comfortable with driving. This is the third car I have owned and fifth one I've drove and by far it is the best. The only thing wrong so far is when I first bought the car i couldn't fill my car with gas no matter how full or empty my tank was without it activating the automatic shutoff, but the dealership repaired that for free.
Mobility is my favorite feature, this car handles way better than my previous cars. Also the 3800 Series II engine is a plus, I believe this is the best engine GM has ever built.
My 03 Impala LS has been great. Excellent fuel mileage (21 avg, 28.5 hwy @ 145k miles). Using Castol Syntec, change when computer says to. Replaced catalytic converter ($800) which seems to be an Impala plague. 130k: transmission started to slip, but nothing serious. Used Seafoam Transmission and most shifting problems went away. 146k: replaced both front bearings ($650). 2.5-3 years: battery dies w/o warning.
Very roomy, HUGE trunk, very quiet touring car. Very low cost per mile to operate, very little maintenance. Super reliable.
Cabin remains hot in the back seat, regardless of air settings. Needs air vents in backseat area. Power steering fluid difficult to check/fill. Needs access tube.
