1977 Mercury Grand Marquis: Cadillac-Baiting Luxury In A Two-Tone Mercury Hardtop

1977 looked like Mercury’s year at last: While its GM rivals downsized, Lincoln-Mercury proclaimed, “We still build them like we used to,” and even invited buyers to compare the full-size Mercury Marquis to the latest Cadillac De Ville. Buyers took interest, but even the posh Grand Marquis remained an also-ran in the hotly contested mid-price segment. Here’s how it fared in 1977.

I’ve remarked before that the Mercury brand often fared best when it stuck closer to the Ford end of the mid-price pool. Lincoln-Mercury had often been reluctant to test the brand’s luck in the upper-middle-class realm occupied by the senior Oldsmobile and Buick models, and their occasional stabs in that direction had missed more than they hit.

However, for 1977, it looked like GM had finally given Mercury an opening. All the GM B- and C-body cars were downsized, meaning that the full-size Mercury was now clearly bigger than the rival Oldsmobile Ninety-Eight and Buick Electra.

The size difference wasn’t as dramatic as you might think without looking at the specs — the Marquis was 6.9 inches longer than the Buick, 8.6 inches longer than the Olds, and 2 to 3 inches wider — but it gave Mercury a unique selling point. Lincoln-Mercury ad agency Kenyon & Eckhardt jumped on it, emphasizing that Mercury was “still building our cars the way we used to,” with no unseemly size reductions.

Probably the most audacious part of the campaign was the above ad, launched in March 1977, which gave consumers a toll-free number to call for more information on a Nationwide Consumer Testing Institute marketing study comparing the Marquis to a Cadillac De Ville. Lincoln-Mercury got about 25,000 calls in the first 48 hours.

The Marquis was now one of the world’s biggest cars. It wasn’t THE biggest; the Chrysler New Yorker and Lincoln Continental were a little larger still. However, the Marquis stretched 229 inches overall (almost 582 cm, for our readers in the metric world) and weighed over 4,600 lb.

There were three sub-series: the standard Marquis, the Marquis Brougham, and the top-of-the-line Grand Marquis. The Grand Marquis two-door hardtop started at $6,880, which was a little bit cheaper than an Olds Ninety-Eight Regency or Buick Electra Limited, although the Olds and Buick included some standard features that were optional on the Mercury, including power windows and a power seat.

This Grand Marquis hardtop has an interesting “Tu-Tone” paint scheme, with a darker color on the hood, lower body sides, and the front part of the roof. On the Grand Marquis, the Tu-Tone option deleted the bright molding normally fitted to the tops of the rear fenders and the otherwise standard padded vinyl roof.

Skipping the vinyl top was an unusual choice for the late ’70s, since it was a very common “luxury” feature. Almost 65 percent of 1977 full-size Mercury production had a vinyl roof, so I don’t think the two-tone option was very popular, but it is certainly distinctive. This is not a car you’d be likely to lose in a parking lot.

The oddest styling feature of the 1977 Marquis was the textured panel on each headlamp cover, which I think matched the texture of the optional vinyl body side inserts. On the Grand Marquis, the covers also had “Gold Marquis” crests.

In back, the “M E R C U R Y” lettering was set into another textured panel between the taillights.

Although even the Grand Marquis wasn’t quite as well-equipped as the senior Olds and Buick models, it offered a good dose of Lincoln-esque luxury for the price.

The front Twin Comfort Lounge Seat, which had been restyled for 1977 to look like bucket seats, had real leather bolsters around its striped velour inserts. (You could also get all-velour upholstery.)

The Marquis had the same two-spoke steering wheel as the Lincoln Continental, although it had a different dashboard that lacked the Lincoln’s secondary gauges.

Mercury advertising made a big deal of the “ride-engineered” concept, which meant old-fashioned softness and isolation. The downsized GM big cars were a bit firmer than before, with noticeably greater handling composure, but Lincoln-Mercury figured there was still a market for the traditional land yacht boulevard ride.

One thing you notice looking at this car is that for all its size, it’s really not that roomy inside. The two-door Grand Marquis hardtop had LESS head and legroom in back than the downsized GM C-body coupes, and the four-door didn’t have any more room than the Buick and Oldsmobile sedans.

The Marquis was wider, so it had a bit more shoulder room, but it still wasn’t very inviting for three-abreast seating even in back. This is part of why GM was so successful in downsizing its big cars: They were better-packaged, so all buyers were really giving up for the smaller outside dimensions was a few inches of width most people didn’t use anyway.

Maybe the biggest surprise in that respect was that the Marquis really didn’t have a very large trunk for a car this big. The usable trunk space was wide and deep, but surprisingly short.

The reason was that Lincoln-Mercury had used carpeting to conceal the spare tire well and decklid hinges. Most of that space wouldn’t have been easy to use anyway, but it seems like a weird choice.

One area where the Marquis was definitely bigger than its GM rivals was under the hood. The Grand Marquis came with the 460-cid V-8, where the biggest engine available on a Ninety-Eight or Electra was now the Oldsmobile 403. However, the 460 engine (which wasn’t certified for California sales) had only 197 hp, just 12 hp more than the smaller Olds engine, and its extra 33 lb-ft of torque was offset by an extra 600 lb of curb weight and an Everest-tall 2.50 axle. (You could still get a 3.00 axle, but this car doesn’t have it.)

The bigger engine also cost you dearly at the pump. The optimistic EPA ratings for the 460 Marquis were 11 mpg city, 16 mpg highway, but Consumer Guide warned that under 10 mpg was more likely, where as an Electra or Ninety-Eight with the 403 could do 13 mpg, and one with the 350 might return 16 mpg. Since the oil embargo, big car buyers were more concerned about fuel economy than they had been in the past, and such outright gluttony was at least temporarily out of fashion.

Still, swimming against the current was a boon to sales, at least for a while. Full-size Mercury sales swelled by almost 60 percent for 1977, to 147,969 cars. However, mid-price buyers turned out to be a lot less resistant to downsizing than Lincoln-Mercury had hoped: Oldsmobile sold 385,331 full-size cars, while Buick sold 377,428. As for the De Ville, people bought it because it was a Cadillac rather than because it could pass a blind taste test against lesser cars; Cadillac C-body sales for 1977 totaled an impressive 266,083 cars.

Most Marquis buyers still preferred the four-door models: the two-door hardtop accounted for only about one-quarter of sales. Production of the two-door Grand Marquis hardtop was only 13,445 cars, so they aren’t a common sight.

If you aspired to a Lincoln Town Car, but couldn’t justify the extra $3,000, the Grand Marquis was a pretty satisfactory consolation prize. In the kind of driving the car magazines favored, it was as out of place as ballet slippers on a hockey rink, but it was good at most of the things it was designed to do. However, the downsized Ninety-Eight and Electra were as good or better, and they were obviously superior in other areas, like the ability to pass a gas station. There was really no advantage to “building them like they used to,” and buyers had recognized that. Eventually, the whole full-size segment would go the same way.
