1998 Mercury Grand Marquis LS 4dr Sedan


I bought the car for $2000 with 86,000 miles on it.
Great car.

At about 118k the plastic intake got a crack in it causing the engine to quickly over heat and warp the heads. This is a problem with these motors. You can look it up on the net. The same motors are found in the Crown Vics
and the 8cy mustangs.
I replaced the motor with another one with about 118k on it which I replaced with a after market intake manifold made out of aluminum instead of plastic. It ran until about 136k it was totaled in a 5 car highway accident during a ice storm.
I took kidding about it being a "grandpa" car but I loved the car.
Would buy again but replace the intake manifold. Best 2 grand ever spent.

Best Features

1. comfortable driving. 2. Leather seats. 3. Safety 4. felt like luxury 5. Low cost for a quality car.

Worst Features

1. Replace plastic intake manifold, otherwise the 4.6L was a built like a rock. 2. Make it front wheel or all wheel drive.
