Previous owner documents

2 sets of GM keys

Pictures not altered in any way

One of the best GNX's in the world, in out AND underneath,


One of the lowest mile GNX's around

Clean and clear title

Several well known stars are buying them.

One of the hottest cars on the market.

Up until the GNX was made, this was the 'only' car ever to be displayed on the turntable in the Corvette Museum other than the Corvette itself


Buick rated it at 276 Horsepower (the magazines rated it at 300 HP), actual is much closer to 400 Horsepower

Deemed the fastest production sedan in the world, and it is an Automatic!.  Beat the Ferrari Testarossa (12 cylinder - 385 HP), Lamborghini Countach and right beside the Porche 911 Turbo (all are stick shifts)

The Ferrari Testarossa, Lamborghini Countach, and Porshe 911 Turbo are all great Supercars and made in limited production, but thousands were made over several years time, whereas the GNX was made for only one year with far less production numbers. 

GNX single turbo V-6 automatic (276 HP), beat the Callaway V-8 Twin Turbo Corvette (375 HP), stick shift, a GM oops

0-60:  4.4 seconds

1/4 mile: high 12's 

These cars have been collectors since day one and are a sound investment, even years to come

Even replacement parts had exclusivity, you had to provide a VIN and (I think proof of current ownership), and turn in the old part to get a new one

Many original parts are not available, even today

The GNX holds up well through weak markets and look when they do in STRONG markets

Now antique status at 35+ years old

On track to be a Million Dollar Car someday

Originally 200 to be made, then 500 to represent the Indy 500 and Daytona 500, (also Buick's 500 best selling dealers). Finally 547 in which the select 60 program to receive, but only "47" were qualified dealers, hence the "547" made.

547 made and for one year only

McLaren took 547 GN's and modified the cars at their plant (partnering with Buick):

GNX Reprogrammed motor and transmission for more boost and tighter shifts

Garrett T-3 Turbo with ceramic impeller, much less turbo lag, quicker spool, higher boost

GNX Custom torque converter and transmission cooler

Unique GNX aluminum rear end cover

Ladder bar, raises rear end for heavy launch

Low restriction GNX dual exhaust with dual mufflers

Functional fender flares/vents

Speed rated Goodyear Gatorback directional tires

Unique aluminum wheels

Biggest tires and wheels available at the time

Stewart Warner gauge cluster

GNX Dash Plaque 

GNX badging

Never molested, chipped, tuned, etc. Not even bolt ons

Last Year for the Rear Wheel Drive Buick G Body

Patent filed for an up and coming new Buick Logo so this one will be a classic

Younger Brother to the GSX


Heated Storage in Winters

Well preserved original car all around - take a close look at the clean undercarriage and compare it others

Will be moved to storage facility for pickup like one shown in the pictures. It is not housed here.

Started up and run to temperature at least 2 times a year, driven sparingly

These are still on the rise and one of the hottest cars if not 'the' hottest car on the market

I bought my GNX well over a decade ago for only one reason, because I was obsessed with it and was my ultimate dream car. I did not buy it with hopes for making or fear of losing money.

Previous 2 owners cared for it for around a decade each. I have owned it for over 15 years, so no flipping or short term ownership.

My GNX has never left the United States

These are expected to increase in value more and more over the years

Values have held steady on the GNX's in the market crash of 2008 and continue to climb to this day


Recently Sold:

Highest public sale for a GNX is $308,000 plus taxes, etc. with over 550 miles!

A gorgeous repainted 6,000 mile GNX sold for $200K plus

Another gorgeous repainted low mile GNX sold for $225K

2 private trades with ultra low miles (under 500 miles) are in the $325K-$350K range

Auction of 2 GNX's reached a final price of $300K+

A private offer for $500K was turned down on a single digit mile GNX, Yes, Five Hundred Thousand Dollars

Some sold for over triple the sticker price when new!

Original GNX's book at $314,900


The last Grand National I sold, when it came time for the carrier to pick it up they said 'This is the nicest one I have ever seen!'. The quote is from the driver who works for a national carrier company so they see many of them. This GNX is one of those examples.


Value has been recession proof  according to the book value and public sales


What makes this a blue chip car: FIRST of its kind, limited production (one year only), world class performance, extremely high demand


A single digit mile one would sell for about 50% more in this condition and they are only going to be worth more in the years to come.

With the demise of the Camaro, would GM revive a GN or GNX? If they do, the GNX will be even hotter and pricier!

Available now.


I do not charge fees or taxes

Currently only one available from a private collector/owner

As is, where is, all sales final

Although the sale will be final, the new owner can feel free to call me well into their ownership anytime with questions or just to chat if they please


Serious Only
