1979 Pontiac Bonneville Coupe: Rare And Plush Bucket Seat B-Body

Right front 3q view of a Platinum 1979 Pontiac Bonneville coupe in the middle of a street, with an inset showing its bucket seats and center console

A full-size 1970s Pontiac with fender skirts, wire wheels, Landau vinyl top, crushed velour upholstery, and … bucket seats? This rare buckets-and-console 1979 Bonneville coupe is the rolling embodiment of the Pontiac division’s ’70s identity crisis, offering the tiniest dash of sport in a sea of brougham-flavored luxury.

I was going to title this post “Bucket Seat Brougham,” but while this Bonneville certainly subscribed to the aesthetic trends of the Great Brougham Epoch, it’s actually a base Bonneville coupe, not a Bonneville Brougham, which was a distinct Pontiac model in 1979.

Pontiac was certainly not the only automaker to use the term “Brougham” as a trim level, but the fact that they did said a lot about the direction the division had taken in the ’70s. The days when Bunkie Knudsen had launched the limited-production, fuel-injected Bonneville convertible to signal Pontiac’s new, sportier, more vivacious direction were long gone.

The downsized 1977–1979 Bonneville was for all intents and purposes a Catalina with a different grille and taillights (newly refreshed for 1979), different wheel covers (replaced on this car with the optional wire wheel covers), and rear fender skirts.

It also had these curious sunburst medallion emblems, one of which served as the stand-up hood ornament.

I’m not going to mince words here: From a stylistic standpoint, I think the Bonneville was the least successful of the downsized GM B-bodies. It looked like Pontiac had campaigned unsuccessfully to build the Bonneville on the larger C-body platform (like the Olds Ninety-Eight and Buick Electra), and when that didn’t pan out, resentfully adapted the design proposals to the shorter B-body. The optional Landau roof treatment didn’t help, making the Bonneville look like it was wearing its hat pulled down over its ears, and, as on the earlier Colonnade Grand LeMans coupe, the Bonneville’s skirted rear wheels made the wheelbase look even shorter than it was. (It was 115.9 inches.)

The Catalina/Bonneville line was the slowest seller of the 1977–1979 GM full-size cars, and it’s not hard to see why. It was an awkward-looking beast.

If you love fender skirts, simulated wire wheels, and padded Landau tops, more power to you — Pontiac managed to sell 179,416 Bonnevilles for 1979, so there was still some market for this kind of thing. However, I can’t really see a good reason to choose this Bonneville over an Oldsmobile Delta 88 Royale coupe, which was similarly priced and notably more tasteful.

I admit that part of my problem is that I still expect a Bonneville to look something like this. It was big, but it had some sporting verve, and it had that exquisite draftsmanship that was the signature of former Pontiac styling chief Jack Humbert (a quality that’s difficult to capture in photos, but very pleasing to the eye). To quote the late Brock Yates, “That, Bunkie me boy, was a Bonneville.”

Tastes change, of course, and there were 15 tough years between that ’64 and this ’79, but would it have been too much to ask for at least a little of the old pizzazz? Some hint of sportiness that offered a perceptible link to the popular Grand Prix and Trans Am, rather than rummaging through the Goodwill donations box of the Cadillac Coupe de Ville? I guess it was.

Which is why the interior of this car knocked me for a loop. Bucket seats and a center console in a Bonneville, maybe — but buckets and console In THIS Bonneville? An unexpected twist, to be sure.

For a car of this type and era, the Bonneville interior was inoffensive — I find it more tasteful than the exterior — but with its bright red velour trim and faux-leather door pull straps, it was anything but sporty.

Unlike many smaller Pontiac models of this era, the Catalina/Bonneville instrument panel didn’t even have an array of small, empty circular binnacles to suggest a vast bank of instruments. There was a “rally gage” option that replaced the warning lights in the right-hand binnacle with real instruments, but this car doesn’t have it.

Bucket seats in a 1979 Pontiac

The bucket seats themselves were shared with the LeMans, Grand Am, and Grand Prix, but unlike those cars, the Bonneville buckets were offered only in plush Lombardy velour, in your choice of Blue, Camel Tan, or this eye-popping Carmine. (The buckets in the Grand Prix were available in vinyl, leather, or Galante cloth, but none of those were offered on the Bonneville.)

Curiously, bucket seats were optional only on the base Bonneville coupe, not on the Catalina or the Bonneville Brougham. (The latter was offered only with an “loose-cushion look” 60/40 split bench upholstered in even more indulgent Dante cloth.) I much prefer buckets to bench seats, personally, and I like consoles, but I can’t see the point of them in a car like this — it’s like finding a gamer chair in London’s posh Reform Club.

In some other year, you might have been able to make this car into a nasty if rather perverse sleeper; being beaten in a street race by a car with fender skirts and simulated wire wheel covers would make many people reconsider their life choices. However, that sort of thing was no longer easy to accomplish, at least from the factory options list. The most powerful engine available in the full-size Pontiac line now had only 160 net horsepower.

This car has the L27 Pontiac 301-2V V-8, with 140 hp, which was the standard engine in the Bonneville. (The base engine in the Catalina was the Buick V-6.) The 301 was available only with 2.29 or 2.41 axle ratios, making its performance that much more lethargic, and it still wasn’t terribly economical — maybe 16 mpg overall.

Unfortunately, the presence of the L27 engine under the hood means the floor shifter is operating the unhappy TH200 automatic. Today, hot-rodders insist that the TH200 can be rebuilt into a reasonably sturdy and efficient transmission, but in original stock form, it was extremely troublesome for owners. The Federal Trade Commission received more than 1,500 complaints about TH200 failures requiring expensive repairs, sometimes after as little as 15,000 miles. In August 1980, the FTC filed a formal complaint against GM over those problems (and several others), which was eventually settled through a 1983 consent agreement.

It was possible to order a 1979 Bonneville on which the buckets were somewhat less incongruous. This coupe is more like it: Starlight Black paint, no Landau top, and cast aluminum “snowflake” alloys rather than wire wheel covers. It also has the L77 Buick 350 V-8, the sturdier TH350 transmission, and the Rally RTS suspension to tidy up its handling manners. You’ll forgive me if I still think it was beaten with at least one end of the ugly stick, but its aura of menace does offer some compensation.

Inside, the black car’s Camel Tan interior gives a more business-like atmosphere, although the contrast between the buckets and the velour upholstery is still somewhat jarring. This car even has the “rally gage” option, making it in many respects a very different sort of Bonneville than our featured car, despite the similarity in their furnishings.

The Platinum coupe has no performance features I can see, and no performance pretensions other than the outside sport mirrors and the buckets and console, which in context seem like the automotive equivalent of red velvet track shoes. Unsurprisingly, only 5,071 1979 Bonneville coupes (around 15 percent) had bucket seats. If ever there was a car that cried out for some kind of cushy split bench seat, this was it.

It’s not that every car needs to be sporty, or even that Pontiac always needed to be sporty, but a medium-priced car needed to be something, especially in a marketplace already crowded with mechanically similar GM siblings. This Bonneville looked like a car that didn’t know what it wanted to be — whose makers didn’t know what they wanted it to be, and were throwing everything at the wall in the hope that something would stick. It seems that nothing did: Catalina, Bonneville, and Bonneville Brougham coupe production totaled only 78,631 cars for 1979, grim numbers for a mainstream GM car line in a pretty good year for Detroit. Maybe Pontiac should have gone all the way and brought back the old “Silver Streaks” that Knudsen had removed 20-odd years earlier.

The four-door sedans did a little better, tallying 117,391 cars for the model year, but that was still nothing to write home about. Pontiac did quite well overall in 1979 — Firebird production totaled an outstanding 211,454 units, the Grand Prix another 210,050 — but the full-size line had lost its way, and wouldn’t find it again until the later FWD versions.

This Bonneville coupe will never be counted among the great Pontiacs, but thanks to its novelty, condition, and relatively low mileage (46,387 miles when these photos were taken), it has retained some surprisingly loyal fans. It sold for a healthy $24,200 at Mecum Kissimmee in January 2026.
