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.
