our expert's take

I’ve been wrong these last few years.

Until very recently, I thought the old bench-seat-and-column-shifter routine was outdated and useless.

My argument: The senior drivers who buy the few remaining cars with this old-fashioned interior don’t need bench seats anymore because their offspring have long since bolted, and any passengers would likely ride in the back.

Turns out there’s another use for bench seats, one that I had forgotten about.

On a recent Saturday night, I took my girlfriend and her daughter to dinner. On the way back, my girl-friend asked if there was a seatbelt in the center of the Grand Marquis’ bench seat. There was. And within moments, she slid over and buckled up. Instinctively, my right arm went around her, and at that instant, I knew why some people refuse to give up their bench seats and column shifters.

Your significant other can’t put her head on your shoulder very easily in a Camaro, BMW or some other model with bucket seats.

Hey guys, let me tell you something: Having your lady sit next to you is a darn nice way to get from point A to Point B.

Long live the bench seat and column shifter.

PERFORMANCE, HANDLING

Mercury outfits the Grand Marquis with a powerful 4.6-liter, overhead-cam V-8 engine and a four-speed automatic transmission. The standard engine is rated at 200 horsepower. If you order the special handling package, which our dark blue test car had, horsepower is bumped to 215.

Lexus is the first thing that comes to mind when you start the engine. The Mercury engine runs almost as smoothly and quietly as the renowned Lexus V-8. It provides strong, but not overpowering, acceleration and refined performance at all speeds.

The four-speed automatic transmission shifts smoothly. A button at the end of the column shifter lets you disengage overdrive, so, if you’re towing a boat, you can keep the transmission from shifting into fourth gear.

Although it’s no sports sedan, the Grand Marquis does offer a very stable and solid ride. You might expect a big, rear-wheel drive sedan like this one to wallow around corners. It doesn’t. The body doesn’t lean or roll much as you round a corner. The handling package adds stiffer springs, better wheels and tires and air suspension in the rear that keeps the car level when loaded.

The power-assisted steering is designed for ease of use. It doesn’t take much effort to turn the wheel; in fact, you can do it with one finger. The power-assisted, four-wheel, anti-lock brakes work well. Traction control is standard.

FIT AND FINISH

Our test car had one of the nastiest flaws I’ve seen in any new car in years. A plastic trim panel on the outside of the passenger-side front door rubbed against the fender whenever the door was opened.

Obviously, all Grand Marquis don’t have this problem. But it was disappointing that a panel installed so badly could have slipped through the quality control inspectors at the factory and then been missed at the dealership, where the car is supposed to be cleaned, inspected and prepared for sale. I imagine a customer would be livid after spending nearly $30,000 for a car and then finding such a defect, no matter how easily fixed.

Were it not for that one flaw, I’d give the Grand Marquis very high marks for quality. Mercury has done a fine job sealing out noise from the suspension system, tires, road and wind.

Adding to the ambience of the quiet ride are those front bench seats, which in the LS model come with leather and are electrically adjustable. The seats are excellent. You don’t sink into them. They’re firm without being uncomfortable. Inflatable lumbar supports help keep you free of fatigue for long periods behind the wheel. Three people can sit up front comfortably.

The rear seats also are comfortable. There is ample head, leg and foot room in the rear for three passengers.

Mercury furnishes the Grand Marquis with plenty of equipment, including a six -disc CD changer mounted in the trunk, a full array of power accessories and a computerized air conditioning system. Buttons on the steering wheel operate the cruise control.

The digital gauges in the instrument cluster are bright green. The speedometer shows the speed in large numbers, so there’s little excuse for speeding. A bar-graph fuel gauge show how much fuel is left in the usual way and also shows how many gallons.

All in all, the Grand Marquis is a pleasing car to drive.

1998 Mercury Grand Marquis

Base price: $23,790.

Safety: Dual air bags, traction control and anti-lock brakes.

Price as tested: $28,415.

EPA rating: 17 mpg city/24 mpg highway.

Incentives: None.

Truett’s tip: The Grand Marquis is a big, comfortable American car with a high-tech, overhead-cam V-8 engine and plenty of creature comforts.

  • Most reliable car I've ever owned

    Bought my used Marquis for 800 $ , 144,000 original miles. Its exceeded my expectations, very easy to work on . Would recommend for long trips. The previous owner had another car and wasn't using my car at all. He basically left it sitting for what seems an eternity. I thought it would need a few things before I drove away , surprisingly not I drove it home the same day . The only thing that bothered me was the leather seats , I switched them out for cloth seats and it feels much better. It does waste a good bit of gas but I'd say its worth it . Ps. Paying homage to one of the last rear wheel drive v8 sedans 👍

  • Love the ride, comfort and style...

    Brought vehicle at a steal of a price. Was pleasantly surprised...has never let me down. It is easy to maintain. Gets well above estimated EPA mileage, esp for it's age...currently has all original 195,000 miles on odometer. The only drawback for this car is the recirculating ball steering under front end. The majority of weight is in front of car and factory ball joints are sealed. For the money, could not ask for a better car. The 4.6l SOHC engine may not be a power house but it is very durable, smooth running, and decent on gas for a car this size. Wish they were still making these vehicles.

  • The Beast

    Have the LS Ultimate Edition with Precision Trac. Bought this car @ 140K, have now reached 200K with no issues other than wear and tear.. had to have a lot of front end suspension components replaced when first purchased, (tie rods, sway bar links, ball joints) as with any car driven in Michigan! Other than that, have only needed oil changes and wiper blades. Driven a full year through all 4 seasons, here's what I think: Drives smooth. Rear suspension air bags were replaced with springs before I purchased the car, so I do not know how it feels with the air bags. Did not know this at first because the car still rides like a cloud. Surprisingly powerful for it's weight and 14 year old age. Engine literally purrs whereas I notice other cars with same age/miles sound like they're dying. If I've got the AC or heater blowing on medium low, I cannot hear the engine anymore. Engine ridiculously quiet. Haters hated initially when I bought this car until they took a ride. People prefer riding in the GM to the 4 bangers. They enjoy the comfortable ride and roominess. Also the premium sound system is a huge plus, I always get asked "Is that stock sounds?" Yes they are! This thing was made for passenger comfort. The back doors have ashtrays! Win! I'm 5'8 and sleep great in this car when I need to at work. Could not sleep in my old Taurus at all. I may get the leather seats replaced with the plush cloth ones since I'm not really a big fan of leather, because it gets hot in the summer and is cold in the winter. With tinted windows, some aftermarket rims, and some wax, the GM doesn't look so much like your grandpa's car anymore. The woodgrain trim on the interior gives it that extra bit of class. Mine came with an aftermarket sunroof. I'm a small dude, so the radio and climate controls can be a far reach. Actually have to "get up" to change things. Does not bother me one bit because I love the fact I have so much space around me in the drivers seat. I keep both armrests up so the front seat stays in bench mode because it's super easy to throw all my work luggage in the passenger seat every day rather than lug it over a middle console like my old car. I like being able to move around and not touch anything like my door or a middle console with my arms or legs. It doesn't handle too much like a boat, but definitely not like a sportscar either. If you purchased this car, you obviously didn't buy it for sporting. Not bad, as I feel very safe driving, but turns kinda wide compared to smaller cars. Has traction control and ABS so no issues driving in rain or snow. Turn traction control off sometimes in snow just for fun! Depends on who you are. I consider this thing the ultimate driving machine because it suits my driving style perfectly. I'm laid back and relaxed, not sitting up close to the wheel with one white knuckled fist driving and the other fist shaking out the window. This car is not for you! I like the feeling where I put the car into drive and it feels like "the beast is unleashed" rather than just putting her into gear. Think it has something to do with 2 tons of body-on-frame with a big V8 lurching forward, whatever it is, it's definitely not like anything else I've driven. I'm really having a hard time thinking of things I do not like about this car. There really isn't much. My next vehicle will surely be a newer G.M. I want to say gas mileage would be the one thing, I average 18-20 mpg during the winter and 21-22 mpg in the summer months. But since I will not give up my V8 power, feel, sound, and the big body style after having experienced it now, I guess I can't complain about the mpg. Oh, car doesn't have an extra power port, just 1 cigarette lighter port. Cup holders can't hold 32 oz energy drink cans. Doors kind of rattle a bit. Wind noise 60+mph. Pedals don't adjust. All very minor things. The 4.6L V8 200HP package never makes me feel short on power. Jumps off the line pretty nicely and surprises people. And it's nice knowing that even though you're doing 70mph on the freeway, you've got plenty of power to pass up those 70mph-struggling 4-banger buzz-bombs. Absolutely love this car. Purchased for $2500, 14 years old with 140K miles. Had my 2000 Taurus for 8 years and never had feelings for that car like my G.M. for which I've only had a year. She's my all American Iron, Assembled in Canada!

  • Fewest repairs of any car I have owned

    I bought my 1998 Grand Marquis in 2000 with 34,000 miles on it. Since then I have put another 120,000 on it and my only expense other than brakes (once) and tires and oil changes was about $500 in front end work. Oh yes, I had to have the cigarette lighter fixed to keep my cell phone charged. I am now burning about one quart of oil every 2,000 miles. I get as much as 27 mpg on the highway. I also drive a Toyota Corolla and while the Corolla is equally--but not more, dependable, repairs to the Toyota cost more than for the Grand Marquis. And there is, of course, no comparison to the ride, comfort, noise levels nor roominess. While the gas mileage for my Toyota reaches as much as 37 mpg, the Mercury is always my car of choice when driving more than a few hundred miles. My next car? Another Grand Marquis or Lincoln Town Car.

  • Roomy Comfort

    This car is very roomy and comfortable and works well for a larger driver and/or passengers. The drivers seat adjusts to a variety of positions to accommodate all size drivers. I find it easy to maneuver and park, even though it is a very large sedan. The trunk is HUGE!
