Pictures not altered in any way

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

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.  Beat the Ferrari Testarossa (12 cylinder - 385 HP), Lamborghini Countach and right beside the Porche 911 Turbo

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 and far less production numbers. 

 Also beat the Callaway Twin Turbo Corvette (375 HP), a GM oops

0-60:  4.6 seconds

1/4 mile: high 12's 

These cars have been collectors since day one and is a sound investment, even years and decades 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 Classic 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 nearly 15 years, so no flipping or short term ownership.

My GNX has never left the United States

Very common 100 year old cars that were made in the millions and even tens of millions are worth close to 20 X the value today

Now figure only 547 made, for only 1 year, and another 1, 5, 10, 15 years down the road.

As time goes on you see less and less with demand always high and supply falling shorter over time. This will increase the value

Many many theories like above but this one is a great example

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

A couple private trades 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

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 GN examples.

Value has been recession proof for the last 15 years+

Put in your living room and the picture in the garage or drive it

I do not charge fees or taxes

Safe and secure private sale from myself, a longtime private collector/owner

Car is ready for purchase

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

I will do my best to reply within 24 hours or less as I am caretaking for 2 patients
