Overall, this is a fine vehicle. The ride has been stiffened up for 2003 but the handling and steering has been improved. My Grand Marquis has been very reliable for me.Some weak points are very cramped rear seating which has taken a toll to give you all that trunk space. The lighting control module has been troublesome for many, resulting in operational issues with the headlights and there was a recall for this. The stereo system is not a great sounding system and could use some upgrading. Gas mileage is decent for a big car. I average around 20 mpg in the city and 25-27 on the highway. These cars sell used at a very low price and are a good value as a used vehicle too. Update 2022- my G.M. recently let me down with only 42k miles accrued. Fuel pump went dead. I know it's old but never expected the fuel pump to fail with so little mileage. Presently, at 48k miles, the transmission is having a harsh 1-2 shift on light throttle after the car has been driven atleast 10 miles.

Beautiful car, comfortable, powerful, reliable. This is my second Grand Marquis ('94). The best used vehicle you can buy period. Good choice for a new vehicle too, but they depreciate fast. Bought it with 30,000 now at 72,000. Only problem: A/C only blows out of defrost.
Nice car but ride could be improved

Air Conditioner worked great. 8 way power seat and back lumbar kept me from getting fatigued on I-95 Plenty of power from 4.6 liter V-8 allowed us to merge safely. Plenty of trunk space for our luggage. Smooth ride on Interstate but a little herky jerky on secondary roads. Plenty of cabin room for us to stretch out 4 speed auto tranny shifted great. I like the outside buttons on the driver's door, in case you lock your keys inside. Spare tire is steel full size rim, and you can use it when you rotate wheels. Remote control from key ring is convienient to lock and unlock trunk lid and doors. Headlights give ample candle power at night driving.
great salesman car

I purchased my Ultimate new in March of 2003. When I picked it up, the fuel gage didn't work right and it took until August to repair this - 3 different times. Then, the instrument panel "flashes" and that has been worked on 6-times now! Still flashes! And, had a sound like I was dragging a tin can. Turns out that the starter wasn't completely disengaging and the starter and flywheel had to be replaced! All this and not a year old and only 7400 miles! What next? I am not a happy camper!
