"This vehicle has it all. I am the second owner and love the ride on the highway and the power on the street. The LT-1 engine is great on gas and very dependable. I have over 90,000 miles on it and have had no major problems with the vehicle. Too bad they don't make these anymore. This vehicle was used as police cruisers by law enforcement and they will tell you it was a great car."
"My husband is a mechanic and we've seen several of these cars come through our shop, and I own an '04 myself. Personally I love my car. It's very roomy for our family of 4. VERY VERY COMFORTABLE! We get 25 mpg in town and over 30 on the highway. I would like to only change the fact there are no rear heat/cooling vents for the backseat. Unfortunately, I've seen lots of problems on other people's Impalas. Transmissions and intake problems are most common. Also problems with ABS systems and wheel bearings. At 83,000, my wheel bearings are already toast and I've had to have ALL my fluids flushed. Dex-cool does NOT last 100,000 miles like they say. My coolant looked like red-ish rust. Intake problems are very common on any 6 cylinder GM car, other than superchargers. That's between 600-1000 to repair. Wouldn't recommend any 6 cylinder GM car to anyone unless they either have a large pocketbook or have a mechanic friend."

"I use to stand by Chevy cars but after reading all the problems other owners had and them being the same as the ones I'm having now, something has to be done. I had to replace the catalytic converter 2 time; had 3 fuel injectors go out; on top of that replace an emission modual as well. This all started after 50,000mls.
