Historic Rare & Extremely Low Miles Original Paint Interior Drivetrain 11sec Car on 2040-cars

Year:1986 Mileage:8379 Color: then cover her back up with a dust cover in the garage

Moorestown, New Jersey, United States

Moorestown, New Jersey, United States

Up for sale is my 1986 Buick Grand National with 8,361 miles and the original paint, interior, engine, trans and front tires.  This is one of the lowest mileage Grand Nationals you will ever find.  I am the second owner.  I bought it MAR 2006 when it had 6,492 miles on it.  I put 1,100 miles on it the first two years and added the remaining 750 miles over the past six years.  I change the oil & lube the chassis every fall with Castrol GTX and a Delco filter.  I drive it during the spring through fall in the morning or at dusk.  After she cools down I dust her off and spray polish the exterior then cover her back up with a dust cover in the garage.  Before getting parked for the winter she gets a top off with 93 octane and fuel stabilizer.  In the spring she gets a can of octane booster.  The car sits on a trickle charger when not in use. Battery was replaced ~ NOV 2013 due to a bad cell.  Car runs strong, doors have that new car closing sound and the A/C is cold. Freon was switched to R-134 when I bought it in 2006.


1986 had a production run of ~ 5,000 units vs the ~ 20,000 units in 1987.

The original owner of the car is a friend of my father's from high school.  He worked for GM and bought the GN from Dearden Buick in Langhorne, PA.  He had a car collection of ~ 12 cars in a 100' long pole barn.  In 2006 he was selling his house and cars to move to another state and sold her to me.


Why am I selling it.... It is time for something new in the garage bay that I am going to have time to enjoy.  With low mileage and original interior/exterior I am really hesitant to drive it.  It is time for someone else to take the reins and enjoy her.

What was done...that I know of.  The original owner did not do any internal engine mods.  Everything was bolt-on.  The original inter cooler and emissions gear are in a box and come with the car. I have to look to see if the original turbo is in the box.


  • 43# Green Stripe Tomco Injectors (410 HP - 545 HP range)
  • TE-44 Turbo (580 HP Max typical) - I think this is in the car due to the original owner circling this model on a data sheet.
  • Bigger Intercooler
  • The GN comes with the stock, street and racing chips.  The street chip is currently installed.  Guessing it is a 'Red Armstrong' Chip given the data sheet the original owner gave me
  • 3" Downpipe
  • Hooker exhaust/mufflers
  • Aluminum Radiator (believe this was for better cooling)
  • Air bag in the right rear spring for traction
  • Engine is ratcheted down to keep it from breaking the motor mounts due to all the torque
  • Adjustable waste gate to dial in the boost
    • 93 Octane with street ‘93’ chip = 18 psi (what it is set at now)
    • 100 Octane with street ‘93’ chip = 20 psi

After adding the mods and tuning, the original owner trailered the car to Atco Raceway (Southern NJ) for a private rental and on the 1st or 2nd pass it hit the expected ETA.  Total passes on the car are no more than six to dial-in the tune with the fastest being 11.962 @ 113.02 mph with 1.701 60 ft on drag radials.  I am including the time slip. The car was tuned to run 11.6's with slicks.  She wears street radials now and never had slicks on due to the fact slicks will destroy a rear.  No roll bar is in the car or has ever been installed. Assuming a 200 lb driver and 3500 lb vehicle, to hit a 11.6-11.9 sec time @ 113-119 mph requires 425 - 470 HP at the rear wheels.


There is minor etching in the door paint under the side moldings and along the trunk edge (1980’s GM products had horrible original paint). I have taken photos to document this. Car has been in a garage for 28 years so it could be a lot worse. It is only original once.


When I was swapping garages last fall, I noticed around the driver’s coat hook in the back the headliner has started to sag. There are a few small sags on the left rear side along with the sun visors showing signs of the headliner glue failing.  It decided to leave it alone to further keep it original. Pictures document these.


No matter how many times I buff the plastic bumper to body inserts the fade always comes back. This is just a product of 28 year old plastic.  It is not cracked…just keeps fading. Pictures document it.


I will be available to show the car locally within a reasonable distance and time. Car is located near Moorestown, NJ 08057 zip code (across from Philadelphia, PA).  Buyer is responsible to ship the car from my place to their destination. I will work with the buyers transportation company to move the car to a nearby location (an open parking lot) for them to load.


Car has a clean title. By bidding, the buyer understands and agrees the car is sold as-is…where-is…no warranties are expressed or implied.


I reserve the right to end the auction early as the car is also for sale locally.


Send me a message via ebay with any questions. Send me your phone number or personal email if you want to discuss the car or need more photos taken.

GM announces six new recalls, covering 3.5 million vehicles

Mon, 16 Jun 2014

General Motors has just initiated another crushingly large recall, this time affecting some 3.36 million vehicles built between 2000 and 2014 and sold in the US, Canada and Mexico. Once again, the issue surrounds the cars' ignition switches, which can be kicked out of the run position if they're carrying extra weight or if they experience a "jarring" event. In this particular case, though, GM will modify the keys, rather than the ignition itself.
A four-by-six-millimeter hole will be drilled into the key, which will more safely accommodate the weight of the key ring. As is usually the case, the work will be done free of charge. The recalled vehicles include the 2000 to 2005 Cadillac Deville, 2004 to 2005 Buick Regal LS and GS, 2004 to 2011 Cadillac DTS, 2005 to 2009 Buick Lacrosse, 2006 to 2008 Chevrolet Monte Carlo, 2006 to 2011 Buick Lucerne and 2006 to 2014 Chevrolet Impala. Only the Impala is still in production, and even then, it's only sold to fleet companies.
According to an official statement from GM, there have been eight crashes and six injuries due to this latest issue. As if this isn't a dire enough blow for GM, the company has announced five smaller recalls, covering 165,000 vehicles.

1969 Chevrolet Chevelle vs 1987 Buick GNX in Generation Gap showdown

Wed, 15 Oct 2014

Generation Gap generally tries to adhere to a theme for each episode, and for the final video from the Lingenfelter collection, the series might have its best idea yet - limited-production muscle cars from General Motors.
On one side you get a 1969 Chevrolet Chevelle COPO, and it's an absolute sleeper. Other than the SS wheels, this classic coupe looks practically bone stock, at least until the engine fires up. Under the hood is a 427-cubic-inch (7.0-liter) V8 making a claimed 425 horsepower and 460 pound-feet of torque. This was the sole year for the COPO package on the Chevelle, and Chevy only made about 323 of them.
The Chevelle's challenger is almost as rare and arguably just as cool. The 1987 Buick Grand National GNX looks just as mean today as when new. It eschews a traditional muscular V8 in favor of a 3.8-liter turbo V6 making a claimed 276 hp and 360 lb-ft, although that number is supposedly a bit underrated. Also, just 547 examples of the GNX version were ever built making it quite a collector's item too.

Buick Envision spied fully disrobed in China

Wed, 27 Aug 2014

The Buick Envision crossover is supposed to have its big reveal on August 28 and be on display at the Chengdu Motor Show, but apparently the new midsize crossover just can't wait to meet its public. Car News China caught a completely undisguised example parking outside of the convention center where the show is held.
The Buick designers are going right down the middle with the styling with nothing too flashy to turn off potential buyers. Still, it's a handsome CUV that kind of looks like a stretched Encore from some angles with vents along the hood, a large greenhouse and a prominent crease running down the side.
This new midsizer is hitting the Chinese market first and reportedly rides on GM's Delta platform that's also found underneath the Buick Verano. According to Car News China, prices there are between 160,000 yuan and 220,000 yuan ($26,000 - $35,800 at current rates). However, it's also rumored to eventually make its way across the Pacific to give Buick buyers in the US an option between the Encore compact crossover and larger Enclave.
