The Buick Skylark 80X was the second major promotional car I did for Buick as Performance Design.

Performance Design (see The Early History of the Buick Grand National and Performance Design) was created as an assumed name for freelance activities with Herb Fishel and Buick’s promotional efforts in the late ’70s. The 80X was featured in Hot Rod Magazine, October 1979. It was called the 80X because the Skylark was build on the new X-body platform for the 1980 model year.

Keep in mind that in the late ’70s the whole idea of what a performance car was, changed because of federal regulations, corporate downsizing, smaller engines, emission and fuel economy standards. Until computerized fuel injection engine management systems would become mainstream, new car performance was very modest by ’60s standards. Buick was struggling with image and an aging customer base, and needed to try and come up with ways to appeal to a broader market. Performance promotional vehicle creation was part of that strategy. Because these vehicles needed to be real cars that magazines would evaluate, they needed to preform much better than stock. That gave Buick the excuse to develop the unlikely V6 as a performance engine. This engine development produced factory performance parts that saw competition in a variety of racing venues, and eventually did see its way into production as the 3.9 liter turbo in the Buick Grand National and Pontiac Turbo Trans Am, and later in an even-fire configuration as the 3800.

Another thing worth noting is that Buick didn’t have any performance platforms like Chevrolet or Pontiac. So we were trying to make a performance car from an up-scale luxury car with conservative styling. It was no easy trick to take a stiffly sectioned boxy notchback and turn it into a performance car. If success is measured in lasting historical significance, then the 80X and the ’79 Century Roadmaster were not successful. But they were building blocks that helped lead the way out of the fog of the late ’70s.

The modeling on the Buick 80X was done at Diversified Glass Products in Pontiac, Michigan by a group of very talented GM sculptors, mostly from Buick Studio. Larry Brinker acted as chief modeler. Other talented sculptors that helped on the project were Al Holgerson, Ted Klein, Dan Curtis, Dave Curtis, and Claudio Bertolini. If I’ve left anybody out, please let me know. We would meet at Diversified and work in the evenings and on Saturday. It was not the best of environments to work in, as it was a working (read: dusty) fiberglass fabrication shop during the day.


This is how these things start. Pretty scary and hard on the sheet metal.

Models always go through ugly stages that tests the designer’s convictions. This car was no exception.


The sculptors were the best anywhere.


The hood blister came out nice. I felt free to break away from the stiff sections of the car and create a more organic form.

Considering that these add-on panels were going to be offered to the pubic, I thought about ways to make the panels easier to install. I came up with the idea of attaching them with a C-shaped rubber molding with rivets instead of a lot of extensive and expensive body work. The C-shaped molding slipped over the flange designed into the body panels The lower leg of the molding went under the flange, and the upper leg of the molding covered the rivets that held the panels in place. The molding also added a visual, graphic element to the panel design. The idea was that the installation would be easier and far less expensive than traditional panel installation methods. I learned later that the shop that installed the panels and finished the car had a difficult time getting it perfect. Oh, well.


I imagine these are rare parts. Like none, maybe.

  1. This post mentioning Diversified Glass Products which brought up a car I’m looking for information on. A GM produced and GM dealership-sold IMSA Monza. Apparently Diversified Glass Products made the IMSA panels that GM stocked and sold to Monza owners that wanted the DeKon look for their street cars. Any chance you had something to do with the IMSA Monza?

  2. No, I had nothing to do with the IMSA Monza.

    As a former owner of what I considered to be “one” of the worst GM cars I’ve owned – and I’ve owned some stinkers – the X-bodied Oldsmobile Omega in brown like the model – no less, I must say it brought back some memories or nightmares!

    I almost spewed my coffee through my nostrils when I saw the final version and the body kits that were made available. But it’s a little like looking at my pictures of the high school prom. I can only glance. (and wince)

    As an bonafide carrier of the TR disease; I’m an owner of 6 current Regals; an original N.A 82 GN; a 86 WH1; a 87 WE4; 86 GN; 87 GN; and an 86 T-Type. I won’t count the 87 that I lost in the ’95 divorce – may she rest in peace someplace safe – I really enjoy reading the history of the 81 Pace Car and the GN.

    Do you have anything on the ’82 GN or was that a C&C effort exclusively?

    I worked at C&C and ASC back in the late ’70’s and had a lot of fun doing the King Cobras in Livonia and some not so fun moonroofed Chrysler LeBarons etc.
    I cut my teeth at the ASC trim plant in Southgate polishing stainless reveal moldings for those gaudy Eldorado conversions. One of those jobs that you look back on and say – wow – did I luck out becoming an electrical engineer!

    Just really was fascinated to come across your webpage.

    I remember as a kid watching George paint this car for the Detroit Auto Show. The Orange fade was amazing.

  5. The 3.8 was even fire from the late 70’s, I believe. Interesting evolutionary split between the fwd motors and rwd motors. Tough motors!
    Sorry, I really don’t like the looks of that body kit – the mid-70’s Regal with a bit of cleanup looks great. (Don’t worry, it’s only a Buick…)
