Exactly What is a LeSabre Grand National?

Many do not even know that Buick Division of General Motors produced the Grand National on a platform other than on the Regal but there was a very unique Grand National built in late 1985 – the 1986 LeSabre Grand National. 117 (or 112) copies were built to qualify the new, first year 1986 LeSabre FWD Coupe body for NASCAR competition. The main reason for building the 1986 LeSabre Grand National was to get the new body with modified rear quarter windows sanctioned for Winston Cup racing that year. The modified windows gave the car a streamline advantage over cars with the large rear quarter windows. All LeSabre Grand Nationals were produced in December, 1985 in one run, from one run sheet – some of the first FWD LeSabre Coupes produced at the then brand new Buick City plant. Serial numbers are sequential or nearly sequential and all have the same exact options. Around that time Buick Motor Division changed its marketing strategy from a performance to luxury car image and cancelled future LeSabre Grand National builds. Only the one production run of LeSabre Grand Nationals was completed and Buick decided to build no more. As such, the 1986 LeSabre Grand National is the rarest of Buicks wearing the Grand National emblem and one of the rarest of all “modern” era Buicks.

LeSabre Grand National Information

Here are some of the details, correct or not, I have gleaned from GM employees and publications, the internet and some old car books over the years:

·         Produced in late1985 only for 1986 model year

·         Production figures are reported by GM at 117 and 112. See interesting comments at bottom of this page.

·         Some prototype LeSabre Grand Nationals were rumored to have been turbocharged but kept destroying the FWD THM440-T4 transmissions so production vehicles were released to the dealers in normally aspirated versions. Buick planned to spend it’s research and development money on other projects and the LeSabre Grand National was limited to just the one run to qualify the body for NASCAR competition.

·         The 1986 Buick LeSabre Grand National was built to qualify the new LeSabre Coupe body for NASCAR competition. All of the LeSabre Grand Nationals produced were shipped to Daytona, Florida for the 1986 Daytona 500 race. Reports are each car received a Buick Motor Sports cooler, seat cushion and pen as promotional give away and that each car was taken on the track for at least one lap. The original factory invoice for my car has an option line reading “24 DAYTONA 500” and the date the car was shipped from Florida to the selling dealer is directly after the race.

·         Some information states conversion to LeSabre Grand National was performed a Lloyd Buick in Daytona, Florida but this is not correct. All were built at the Buick City plant in Flint, Michigan. The cars were not sent to a third party for completion as was 1987 Regal GNX and many other specialty cars - all were completed by Buick. The front spoiler (facsia) was not ready when the cars were were produced and regular LeSabre front facsias were installed and the cars were shipped to Daytona that way. Buick shipped the correct spoilers to Florida and all cars had the correct spoiler inatalled at the Lloyd Buick dealership in time for race day.

·         I have spoken to several Buick employees / ex-employees who were able to see the cars when they were built. The LeSabre Grand Nationals were batch built in the same week or so at Buick City from one order sheet and all alike. After build the cars were stored in Building #94 at Buick City. One Buick employee I spoke with was assigned the task of checking for mis-builds and insuring the rear quarter window close-outs were correctly installed. He is positive that there were actually 119 of the cars in Building #94, all black except for one that was red. He thought the red car was a mis-build. The car was completed with the black cars and went to Bobby Allison / Miller team.

·         LeSabre Grand Nationals were slated to be sold in the Atlanta, Georgia and Jacksonville. Florida zones after the Daytona 500 - areas to the Daytona 500 race facility

·         Buick Documentation States Model Available in Black (41) and White (40) - white was not produced although one red one was. One picture of a white car appears in the 1986 LeSabre Grand National sales brochure. However, the white car pictured appears to be a LeSabre Limited with LeSabre Grand National emblems and window closeouts and was probably a pre-production car and was for the photo layout. The black car in the same brochure and other GM promotional photos sports a regular LeSabre lower fascia, not the one released on production LeSabre Grand Nationals and it too appears to have been a pre-production car.

·         P37: All are based on the LeSabre Custom Coupe

·         WE2: Grand National Option - $1,237

·        B Pillar Appliqué (Black)

·         LeSabre Grand National Fender Badges - Turbo-Six was all red, instead of Regal Grand National's traditional yellow and red. This supposedly was done to differentiate a turbo from a non-turbo version. The Red Power Six emblem was available and had a separate number but the documentation incorrectly lists the part number for the Regal Grand National emblem

·         Blacked Out Trim - however, bumpers, grille, headlight surrounds, wheel well opening trim, roof drip rail, door handles, locks and trunk emblem surround are chrome, smooth rear bumper - no bumperettes

LeSabre Grand National Rear Quarter Windows


Left: Rear Quarter Window Closeout. Right: Louvered Cover Was Not Just a Trim Piece

The louvered rear quarter window close outs were critical for the production car so that the closed out quarter window could be

used on LeSabre NASCAR racers for better aerodynamics. They were not just a plastic cover - window glass was re-sized,

remaing area was closed out and area covered by a louvered piece. The LeSabre Grand National was produced only for

the 1986 model year so later year NASCAR LeSabres and Oldsmobiles had to use the full sized rear quarter window.

My 1986 LeSabre Grand National

I have been a “fan” of the 1986 LeSabre Grand National since my first two (and only) sightings. The first was outside what is now Dan Marino’s restaurant in Coral Springs, Florida around 1989 or 1990. The second was at a junk yard in Hollywood, Florida about 2002. I wonder if the car outside of the restaurant was the same car as in the junkyard only a few miles away?


Anyway, after years passed I was finally able to purchase one for myself. As the proud owner of one of the 117 (or 112) 1986 LeSabre Grand National Coupes I am putting together all of the information I can find on this rare car. I have my dealer invoice, the LGN brochure, a factory LGN photo, the LGN magazine ad, original photo used for the brochure, factory documentation that includes photos of the 1986 LeSabre Grand National, Skyhawk T-Type, Century GS, LGN, Riviera T-Type, Somerset T-Type and the Regal GN. I will be updating the LGN page on my website to show some of the information I have been able to gather.
