Pros: Good basic transportation, plenty of passenger room, leg room (front & rear), easy to drive), large trunk and reach through back seats, interior cabin lights lacking, inexpensive to buy and maintain.
Cons: No cup holders in the back.

Great overall car that I inherited from my folks.

What can I say this is a very very good car if you are wanting plenty of passanger room,leg room,with excellent gas mileage. I have owned this car for one year. It has great power for when I need to get up and go. My only two complaint on this car is that there are no cup holders in the back seats??? And the driver front door is not very wide. I find my self having to be careful not to rip my pockets of my pants and gliding into the car.

Overall I am very happy with this car.

I've had this car about a year now and so far it's been pretty good. I was looking for a car that would be cheaper on gas and more reliable than my SUV and this was a good choice so far. Aside from regular maintenance, only a few problems. About a month after getting it would not start and took it to the dealer and was fixed at no charge. Under heavy acceleration the tranny doesn't want to shift until 5000 rpm (1000 before redline). On the positive side, the car is very easy to drive, a pretty comfortable ride for Michigan roads, and the E85 option for fuel, though it decreases mpg is nice for the environment

Bought 2 2008 Impala LT's this past November. Both were used........23k miles. Excellent Condition. Both wife and I have only one complaint and that is for a car with a cabin so spacious........very few storage areas. No drink holders in the rear. Interior cabin lights seem to be lacking. Other than that...we love both cars. I installed a K&N Airfilter on both are we are now averaging 34mpg on the hiway. In town MPG is roughly 26. Can't complain at all. We both had 2005 Malibu's. Wife had the Malibu Maxx which the MGP absolutely sucked while mine........the LS sedan was getting around 34. Both cars seemed very powerful. Even though the engines in the Impala's are the same 3.5lt v6 the Malibus have.......they are not lacking for power at all. All in the transmission.
All in all we both love our Impala's......just the ride itself compared to the Malibu is enough to make us glad we switched.

Love this car. Tons of thoughtful little amenities. Inexpensive. Very safe. Great gas mileage for such a generous mid size. No repair or maintenance problems except the horn broke. Only oil changes for the last 50,000 miles, and the car tells me when to change the oil! Sweet. Only about every 7-8k miles! Totally saving a mint on maintenance. One other thing, and this is probably because I don't wash my car very often or keep it in a garage, but the paint is isn't in very good condition anymore.
