This is a reliable, still stylish car that is easy to fix, utterly comfortable and a delight to drive. Bought it for a few hundred dollars, and took a few bucks to get it up and running like new!

I agree with your comments on the car. I have a 1986 Grand Marquis LS coupe. The car color is Medium Shadow Blue and it has every option. I love this car with all my heart. It has been in my family since it was purchased new. The car now has 68,000 miles and is running well. I will continue to baby it and am looking forward to a full restoration. Start searching for new old stock anywhere you can because many OEM parts are being discontinued. My advice is that you hold onto this car as long as possible. Good luck.

If it's got the vent windows, keep it forever.

1986 Mercury Grand Marquis LS 5.0 Liter 302

Summary:

A truly wonderful full-size luxury-mobile!!!

Faults:

The rear driver's side power door lock motor died and was replaced.

Original battery and tires needed replacing shortly after the car was purchased.

Intermittent knocking resolved by replacing ERG valve and doing major tune up.

Rear differential leak resolved by replacing pinion gasket.

General Comments:

I've owned this car for nearly six months now, and I'm very impressed with its ride and handling considering its age. It had only 41,000 miles when I purchased it. The car was well-taken care of by its one previous owner.

I've only had to do routine maintenance work on the car, and the engine runs as smoothly as my 96 Town Car. The car is solid inside and out, and appears to be a well-manufactured luxury car. Ford definitely knows how to design and build their full-size cars for the long haul.

So far, it has been a wonderful second car and I feel safe driving it anywhere considering its above-average reliability and overall well-built design.

They are beautiful cars. I own one with 57,000 original miles on it. Ford has never built a better car. This is the fourth one I've had. They were all very good, but this one is the best.

I agree with ya there. The Best. I've upgraded the AC System totally and aside from that... some small, self installed parts... this car now has 150,000 miles and going strong. Luxurious inside and out... aside from the vinyl top, which has deteriorated somewhat. I take this car anywhere and would drive it to coast to coast tomorrow if I were going.
