1999 Mercury Grand MarquisVisitor, Plymouth, NH, December 04, 2013 14:36I have had this car for only 6 months and already i've had to replace my alternator, my intake manifold, and my bearing. It only has 75k miles and mechanics keep telling me "it's in great condition" but considering I've dropped more money in 6 months on fixing it than I paid I would consider it to not be in great condition. Awful gas mileage, heat takes forever to start, etc. Would not recommend to a friend.
1999 Mercury Grand Marquisblk rate, Glendale, CA, October 16, 2013 15:34My 1999GM-LS runs well now 140,000 miles since new. Had AC control unit, fuel pump, Idle air control valve, rotors, cracked intake manifold replaced. Recently a slight vibration developed at idle when engine is hot. Most noticeable at steering wheel. Dealer can't find fault - deemed normal? Cracked intake manifold - is bound to happen when plastic bonded to aluminum. Grade school physics tells us that metal and plastic expands and contracts differently when temperature changes. can't believe any Ford engineer could overlook this?? when the GM was designed. Perhaps the plastic manifold are designed to fail!Enthusiast

1999 Mercury Grand MarquisVisitor, Kirkland, WA, May 06, 2011 19:01Best car I ever had (and I had over 30 so far). Bought it used with 163,000 miles, and it drives way better than anything else I know.
1999 Mercury Grand MarquisVisitor, Warrior, AL, April 11, 2011 13:27Got my car 2nd hand at 120,000 miles. Just got 270,000 miles on it last week, avg 550 miles a week to work and back home. THe problems i have had are cracked intake manfold (plastic), air compressor, ac/hvac control mod ($500 new, $50 savage), and need to replace rotors (still first set). One coil pack to the spark plugs went bad, still drove on 7 cylinders (till i mad to to the shop). Still avg 23 mpg. The cat is starting to go that will be expensive. I love this car wish i could get another to replace this one when it finally dies.
