General Comments:

I bought this car because I needed a cheap daily driver. Vintage cars are a hobby and I like traditional American luxury cars, having owned a few of them.

The Grand Marquis is very cheap to buy, easy to fix, reliable, and roomy, with reasonable performance and mileage. My car has lived up to all those points.

My car had all options except leather seats. It was well cared for for most of its life, but the last owner neglected it and drove it into the ground. I bought it cheap, $400, but it needed a lot of work. It's rust free, great paint, and the major mechanical components are very solid. But a lot of the wear items were worn out. Fortunately parts are cheap and it's easy to repair.

I chose a '93 because it has the redesigned aerodynamic body which is very quiet and solid. But it had the simple and reliable OBD1 engine management system, and an all aluminum intake manifold. Cars '95 and newer have the more complex OBD2 system and some have a failure prone plastic manifold. Also in later years, Ford made the cars a bit cheaper and removed or cheapened some basic equipment. The older MGMs often handle and perform a bit better, and are better trimmed than newer ones.

This car feels very retro. It's big, wide and roomy, with flat seats, wide dash, no console and a column shifter. I think the seats feel too hard and flat, not form fitting and not pillow soft. But the 8 way seats and power lumbar support help. The head restraints are too low for me, even when extended. The back seat is very comfortable. Leg room in the back is okay, but not much to spare. Still I've had 3 across in back with no complaints.

The trunk is huge and deep. Ford has been making these wonderful deep roomy trunks in their full size rear wheel drive cars since 1965. Best trunks ever.

Unlike many new cars, the dashboard is low, the windows are big and visibility is excellent. The side mirrors are amazingly big and useful. The optional digital dash is much better than the base instruments. It has some gauges and a decent trip computer. No tachometer, though. And the coil pack system requires an adapter to hook up an aftermarket tach. The engine is so smooth and quiet, it's tough to judge the engine revs by sound.

The engine is no huge powerhouse. Power is adequate for normal use, but it's no race car. Like many overhead cam engines, it has less low end torque than a decent pushrod V8. But the top-end power is decent. It's efficient too. This car gets better gas mileage than older models, in part because the engines's OHC combustion chamber design is more efficient. The engine is very very smooth. No vibration gets through and it's really quiet.

The stock single pipe exhaust is really undersized and restrictive. Dual exhaust was an option which improves power... But Ford should have put on duals or at least a big single pipe as original equipment. It's a waste to spend money to develop a sophisticated engine just to kill the power with a cheap exhaust pipe.

This car had the first year of the electronic shift AOD transmission. The shift program is odd. Accelerating from a stop at light throttle puts you in top gear with a locked converter very quickly, and the car then feels very sluggish. I've taken to using more throttle so it shifts in a more normal manner.

This car had never had a transmission service when I got it. I changed the fluid and filter (and drained the torque converter too - Ford nicely installed a special drain plug for this). The transmission had a very long and slow 1-2 shift. The trans service fixed this problem.

The cruise control does not work. There was a recall on these. This car had the recall done, but apparently it needs a special wiring harness replaced for the cruise to work.

Handling is remarkably good. I installed the optional wider 225/70 tires which improved cornering. It has lots of grip to corner fast. The car has surprisingly fat front and rear sway bars for flat cornering. The front bars have some neat, sophisticated ball-joint end links, for low friction and maximum effectiveness. It's a nice detail.

This car is full of nice details like this, where it's been upgraded over the usual traditional American sedan. Rear disk brakes, with separate parking brake drums, standard ABS, double seal doors, 2 kinds of keyless entry, fully carpeted trunk, high quality interior materials, aluminum full size spare tire, aluminum hood, all nice details.

The steering is light, a bit vague and over assisted, compared to a newer car. But it's precise with some road feel. The solid rear axle works well, and handles heavy loads nicely, but is not so good for rough roads. Bad pavement produces a rougher ride than an equivalent car with independent rear suspension.

Overall, I love the car. It's got the roomy retro full size sedan feel, but with all kinds of improvements and upgrades. It's very useful, comfortable, affordable and easy to live with. And it's cheap. This car is the best kept secret ever. No one wants them because they think they are too big and old fashioned, only used by old people... Ah well, that makes it even cheaper for me to buy them.

Excellent review!!!

The pre-95 Modular V8 had a very open combustion chamber - prone to ping, not much flow.

The single exhaust does the engine no justice - duals all the way!!!

Keep up with transmission services and all will be well.

No OBD2 until 1996.

A much better review than anything from Motor Trend or Car & Driver!

1993 Mercury Grand Marquis GS V8 from North America


Nice and comfortable for the money


Replaced plug wires and gas filter, runs much smoother.

Had compression test and checks out fine.

A/C low on freon, but the compressor runs, will address this another time as it has a leak somewhere.

All windows and door locks work, and very nice after market radio.

Paint is faded some on hood and truck.

General Comments:

We needed an inexpensive older car for transportation, and after we found this car, checked out this web site for reviews.

Pretty much everything I read was correct, just a good tune up and it makes a good runner, gas mileage not bad either. Pretty much on mark of 18 city and 26 hi-way

I used to own a '93 GS. I sold it about 3 years ago because the frame was very bad on the passenger side. Typical rust area.

A cheap luxury car with some punch!


The car started missing bad so I had to get a set of spark plug wires which were close to $60.

The belt tensioner pulley bearing went out unknowingly. It went a whole summer and soon discovered a hole actually wore into the motor. A new bearing and cold weld fixed that.

For some reason the motor idles really high. (I think it's a vacuum leak)

Just recently all interior and dash lights and radio won't work.

General Comments:

These are beautiful cars. Mine is the loaded model with sunroof and awesome leather interior. Tons of room everywhere. The air suspension is awesome, I never had a smoother ride. The motor is also very well suited. There is plenty of power from the overhead cam V8 and going to the rear wheels is just cool. These are among the quicker cars on the road. I definitely would love to have a new one.

I have got a car just like yours, and I also have to agree that it is a SMOOTH ride. I go over bumps and hills and you can barley feel them. I love it, all my friends have 4 cylinders and my V8 can take them all. Just wanted to say that you are right about the things you wrote.
