I have owned 6 Impalas since 2000, 3 base models and 3 Ls sedans. We have owned the 2000, 2003, and now the 2005. We have had virtually no problems with any of them. They are very dependable, comfortable, and get good gas mileage for their size. Safety record is also a major plus. It is a great car for the money. I have owned Cadillacs, Mercedes, and Ford products and I can say without a doubt that the Impala is a trouble-free car in every respect. Would recommend it highly to anybody.
Fast, yet easy on gas. If it "aint broke" don't fix it.
