The 2007 has lost of neat extras and they are mostly driver enhancements such as direction, mpg avg, mpg instant, temp outside, etc. I will be honest and say that I like the interior lay-out of my old 2003 Impala much better and this car seems smaller inside. But, I do like the steering wheel in the 2007 over the 2003 model, more comfy on the hands. The trunk is definitely smaller and does not have the back seat pull downs that allow access to the trunk or longer storage for those items that just don't quite fit in the trunk. The exterior of the 2007 is more sleek and sporty but I really like the look of my old 2003 better. The car is still amazing on mileage as I generally avg 30+ mpg.
Put the back seat pull downs back in. Add better seat adjustments to passenger seat. Add the strap for grabbing to close the trunk back in. Add a small pull out tray/compartment for loose change, etc to the console... the ash tray used to serve that purpose.
Electronic nightmare started with tire monitor system and went downhill from there. Dealers don't know how to fix. Replaced multiple transmissions. Had to sell after 18 months. Spent more time in the shop than on the road. A little more cash will buy a reliable BMW. Don't waste time on the SS.
Traded in a 2004 Impala for my 2007. Loved my 2004 so I figured how could I go wrong? Well, I was wrong. Very disappointed in my 2007. Seats (leather) are terribly uncomfortable, radio reception stinks, gas mileage not what I expected. My '04 with a 3.8 V6 got better gas mileage than this 3.5 V6 does. Terrible. Down to 22 mpg. If I need to pick up speed quickly it hesitates before it decides to go anywhere. Not enough storage space for CD's, etc. Wish I'd kept my '04.
Interior room, large trunk, sharp looking car, rides fairly smooth.
Needs larger side mirrors, less blind spots, can't see around head rests when I turn my head, better cup holders, improved sun visors, High beam headlight switch is clumsy, shall I go on?
My wife and I have owned several Chevys in the last 30 years and the 07 Impala is the best. We average 27 mpg and on the highway if we run around 65 mph can easily get 30 mpg. There have been zero quality problems and I believe that this car is the most "bang for the buck". I have been telling family, friends and strangers about this car. Wish I was selling them. Car sells itself.
This is a company car and I've put 45k on it in 15 months. Had problems with tires and they don't seem to keep in balance. Lot's of car for the money and the gas mileage is excellent for the size of car. Six cylinder is peppy and relatively smooth. Went from a Lexus to this car, but not too bad for the cost of the car.
