1989 Mercury Grand Marquis 5.0 V8 302 from North America


I want to do a donut!!! Have no gas!


Well, I usually don't go American with cars, but since Japanese car are expensive so far because of their fuel economy, I bought a Ford pig (Mercury Grand Marquis).

I got this car for my 18 birthday and the car is holding up so far. I did a major tune up (fuel filter, air filter, spark plugs and wires etc).

The car some how runs a little rough sometimes, the engine shakes at times and it stalls on me. If somebody can help me and give me any advice on how to make it run smooth, I would appreciate that.

I got the car for $550. The car is a fun to drive and I can't wait to do my first donut with it. I been offroading already and I love it. I know it's not a rally car, and who cares, my general concern is the roughness of the engine at times, so please help me!!

Would you buy another car from this manufacturer? Don't Know

You should definitely join www.grandmarq.net!! There's a wealth of tech info there :) In the meantime, keep on driving the box.

Maybe it will start to run better when you stop beating the crap out of it. Why bother fixing it up when you'll have it wrecked in a month, anyway?

A very fun car


Alternator went at 310,000.

Blows oil uses about a quart a week.

Transmission slips a little of the start.

Car does unbelievable brake stands.

Comfortable for long rides.

Great on the Highway.

Gas hog.

Basically you can beat this car all day and it comes back for more!

It's not only comfortable and spacious, it's powerful and a delight to drive


The power-steering pump had to be replaced.

The left rear window motor had to be replaced.

General Comments:

I was offered this car in a deal I couldn't refuse. I was first impressed with its imperturbable ride and the quiet, smooth engine; however, I was concerned that because of its size, it would be not only be a gas hog, but would also have poor handling qualities.

I have since discovered that on the freeway even at speeds of 75 mph (speed of traffic) interspersed with stop-and-go traffic, I get between 22 and 24.5 miles per gallon. Not only that, but the more I drive it, the more I appreciate its ability to maneuver and corner. While it's no muscle car, it's eminently capable of staying with the flow of fast-moving, competitive freeway drivers, if you take my meaning.

If I'm not watching the speedometer, I find I cannot tell the difference between 55 mph and 75 mph merely by listening to the sound of the engine and the wind.

The manual seat cannot be brought to a fully upright position. There are no cup holders. There are no map pockets on the backs of the front seats.

On washboard surfaces, the car delivers a very bumpy ride. On a smooth highway, it's like a canoe on a glassy lake.

The glove compartment is indeed small, and the trunk is indeed large.

Why the bumpy ride? If I buy a car like this, it's for the smoothness over the bumps.

The bumpy ride is from, I believe, the solid rear axle. It's noticeable on speed bumps and washboard surfaces on which both wheels come in contact with a bump at the same time. The front suspension in which the wheels act independently from each other is much smoother over these types of surfaces.

I have since discovered that at 109,000 miles the transmission needs to be repaired at a cost of $1495. I have elected to trade the car in. It's a nice car, but I'm more enamored of my money.

#1 Somebody is trying to rip you off with that transmission quote.

#2 If it's bumpy/bouncy, that means the poor thing is crying for new air-shocks.

1989 Grand Marquis are not equipped with air shocks that option was started in 1992.

No, actually air shocks were available on the LS trim in 89. Dig a little deeper before before advising on inaccurate information.
