I have had 3 Grand Marquis. A 1985 that I drove to 250 K! A used 1990 that I drive to 200K. The last car was a used 1996 and in has 98K on it. No problems a good solid cars. 2011 is the last year. This was a great car from a generation ago, well built, cheap to run, and it will be missed by me.
Good highway car, no major repairs.
The steering is too light. It can get away from you.
My 1996 Grand Marquis now has 79600 miles on it and it still runs strong. No one would guess its age (especially since new ones look simliar). Good accelaration and pick-up, lots of power. I have had to have all the O2 sensors replaced, and the mass airflow sensor has been replaced twice. It still has its original battery. I have also replaced the spark plugs. I change the oil ever 3000 miles. Fuel economy is good for the engine size but still very expensive to use for city driving (I get about 16 mpg city/23 or 24 highway)
Keypad (I don't know how many times it has saved me from having my keys locked in the car). Lots of room.
Front bumper is very poorly designed. Seats could use a little more support
I bought my grand marquis used with about 87,000 miles for $2000. I replace the wiper blades, one rim with curb damage, and one missing side light, and changed the oil. It drove great till 117,000 miles. Then the plastic intake manifold cracked, leaking out the coolant. You can read more about this by googling intake manifolds, grand marquis/crown victorias. My engine must of over heated and warped or cracked a head. I don't blame my car, I blame Ford. I bought a used 4.6 engine with 118,000 on it and using info I found on the internet and my library, I switched engines. I have no experience doing this and it took me about 50 hours total. I now have 125,000 miles and it runs great.
Reliable, comfortable, safe, large trunk, the LS is loaded with options.
I would buy another in a second. The newer models don't have manifold problems and if it was the older models like mine I might replace the manifold with a new one. Its not hard and you can get instructions by looking on line.
Bought the Merc at 70,000. Car has been the most reliable I have ever owned. Wife loves the soft ride. I wish it had a handling package. Fuel averages 24 on highway. Good for a Big car. Interior is very comfortable. Cupholders block Climate control access. No problems at all. Still has original Starter and Alternator. I will buy my 3rd and 4th GM soon. I will get LS model for my wife and I will get a used Marauder for me. Great Car!
Good torque and power even with high mileage. Great Reliability. Good in snow for a rear drive car. Tough as nails.
Tachometer. 6 speed transmission for better highway mpg. Bucket seats and floor console. 17 or 18 inch tires. Audio controls on Steering Wheel. Pass thru rear seat to the huge trunk.
