I have had literally no problems with this car and drive it daily for business. It has been the best vehicle I have ever owned. In terms of regular maintenance, the first set of brakes and rotors were replaced at 70,000 miles. A tie rod was replaced after damaging it going over a railroad crossing. No fault of the car, and no other damage.
This car has been super. It handles well, is extremely quick, and has superior handling on icy roads. I am disappointed that Chrysler changed it so much when they went to the new 300. My only complaint has been fuel mileage, which is no better than a small V-8. Other than that, this is a car that I will remember as one of my best. It's also a great looking car. One of my friends said it best when he looked at it parked next to a Buick LeSabre (which I owned prior to this). He pointed at the Concorde and said, "this is a jet plane --- that's a locomotive". Couldn't have said it better.
HaHa, that comment is great! My parents own a 2003 Concorde and it has never had a problem, I believe its currently at around 135K-ish because they travel quite often. I own a 2002 Intrepid ES and both of them still look much better than my grandparents Buick Lucerne, which I think is Hideous!
