The major problem with the 99-04 Concorde and its cousins LHS,300M, and Intrepid was the 2.7L engine. If you did NOT change the oil every 3,000 miles it built up sludge which caused engine failure between 50,000 to 80,000 miles. If you and your husband have the 3.2L or 3.5L V6 then you'll be okay - JUST maintain it regularly. There are no exceptional "trans"problems except by those who fail to maintain them and abuse them. Other than that, most people enjoy them and it is a steal for a full sized used car becuase it is undervalued even with the better engine. Great interior room and ride. Battery is in an awkward spot (front lower right - you take the right front wheel off to get to it!) and corroded battery cables can cause weird electrical problems. Take care of it and it will serve you well.
