I bought this beautiful Grand National on eBay Motors in January, 2010 from an owner in Florida. I've had extensive work done on improving performance and really having it idle and run smoothly and get decent gas mileage. I haven't raced or had this at the strip. Out on the interstate I do like to ease up on German sedans and new Camaros and Mustangs then see if they can pull away….they can't. I had long conversations with the owner before I bought it and most everything he related was true and accurate. The core of our discussions accepted the fact that this is a 1980's vehicle, a G-body that shake-rattle-and rolls. I've done some things to tighten it up, particularly in the front end, but it still makes some racket over very harsh surfaces.  That's just the way it is.


It came with a beautiful repaint, but since I have driven it 25,000 miles since I got it there is some road rash on the front air dam, grill and front painted surfaces, but no dents, cracks, hazing, or scratches. It could use a professional buffing using a reciprocating buffer and compound. There is no rust of any kind on the body or undercarriage and I don't drive it in the rain or snow so from November through mid-May it sits in the garage and I drive my battered Totota Echo, a coffin on wheels. Fit and finish overall is pretty good for a G-body, no wide or unusual gaps. Windshield is clean with no scratches or chips.


The interior has a new headliner, the footwells and carpet or spotless with no wear. The previous owner installed leather seat covers and door panels by JAX Interiors in GN color scheme with turboBuick logo stitched on the head rests. I do not know the condition of the seats. The seats are firm and tight with no seat noise, front, back or lateral movement issues. The dash is clean and perfect, no cracks. Has a JVC radio/CD deck. Only the back speakers work.


Here is a list of items and info provided by the previous owner:


NEW MOTOR installed in 2006. When I got it there was 900 miles on the odometer. Current mileage is 26, 690

Applied Technologies Research (ATR) Hydraulic Cam RP314B…214/208-109

Applied Technologies Research (ATR)  Stainless Steel Headers

51 Precision Turbocharger

42 injectors

Larger (than the Garrett) Precision intercooler

28 stall spped converter

342 rear end 

Larger sway bars

ATR coil springs

4 coil radiator.


Portland Speed Industries is a master race and tuning shop in Hillsboro, Oregon. I had them do the following work (receipts provided with sale):


Idler arm left/right tie rod assembly                                        adjustment sleeves

Center link sway bar bushings                                                  sway bar link kit

Rear main seal Oil pan gasket                                                         oil pump R&R


Valve cover gasket manifold gaskets                                                     turbo outlet gasket


Tranny filter kit Flow Master resonator                                            repair fuel injector


Alignment   Custom EGR plate                                                  oil pressure switch


Completely new wiring harness under hood


R&R machine heads   Performance intake manifold                                  camshaft position sensor

Ignition module Multilayer head gasket (4.06)                                  alternator

New head studs


PSI  did dyno runs before/after. Proof of results provided on sale or go to PSI's website and look in dyno archives: Engine produced 350hp at the wheels and 401.36 torque at 11 lbs of boost.    Any low mileage GN for sale, under 75k miles, is going to need all this work done in short order  due to tremendous under-hood heat that wears out components and quality of OEM parts. If you know about GN's, they are high maintenance vehicles compared to a Honda, but they offer performance opportunities which can be tempting. I have kept mine to a minimum so I am not selling a "racer" or "dragster" or some kind of backyard mechanic modified car.


I run Mobil 1 and engine idles smoothly and rumbly (has a great sound of course) at 10-15 psi oil pressure  hot.   


Other notes to consider:


Wheels are perfect, no rust, dents or flaking. 3" cold air intake and down pipe. Horn works!

Tires are Mastercraft Avenger Touring with 10K on them.

Windows are tinted.

One of the photos shows an original newspaper ad to be included.

Video recorded on a chilly morning and condensation is coming out of the pipes, not smoke.


ITEMS NEEDING ATTENTION:


Shifter handle will need a repair kit. Handle is wobbly and can be pulled up and off. Just haven't done it-about $50-$75. But it shifts fine.

Speedo is starting to buzz and jump a little.

New Buick Envision model spotted in China, expected here this year

Tue, Mar 17 2020

At GM Capital Markets Day in February, GM North America president Barry Engle said the U.S. market can expect "updated models of Chevrolet Equinox and Traverse, Buick Envision and Enclave, as well as GMC Terrain." We've seen the Equinox and Traverse, and although we weren't aware, we've seen the Envision. Buick showed an EV crossover concept in 2018 called the Enspire, and it was thought to preview an eventual production model called the Enspire that's been spotted in various places testing under heavy camouflage in the U.S. GM, in fact, applied to trademark the Enspire name twice in the U.S. The model's final production form got an early reveal in China thanks to the Ministry of Industry and Information Technology, and according to GM Authority, a branding redirection has led to the crossover being called the Envision. Assuming this is the model that comes to the U.S., it will share dealer space with the current Envision imported from China. Motor1 writes that Chinese site Auto Home alleges the name Envision S will distinguish the new product, and the tailgate in the low-res photo plausibly shows an S after the model name. That doesn't mean it would get the S suffix here, though. It's not clear if the coming crossover grows in size compared to the standard Envision the way the Encore GX expanded a touch over the Encore. The marquee difference will be that the new Envision is more luxurious in looks, equipment, and features. There are few details, but it's thought the Envision S sits on the same E2 platform as the Cadillac XT4, and will use the same 2.0-liter turbocharged four-cylinder in the Cadillac paired with the automaker's nine-speed automatic. In the XT4, that mill produces 237 horsepower and 258 pound-feet of torque, but across all its applications in the GM stable it makes anywhere from 230 to 237 hp.    What we can see is that the new CUV takes the Envision name in a more dynamic direction, starting with a trim upper front fascia that puts narrow headlights astride a wide grille clearly derived from the concept, the lower front fascia with chrome-lined outer intakes that recall the Aston Martin DBX. A diffuser-looking silver trim piece in front is mirrored in back. A sloping roof helps create the slim profile, leading to a trim backlight, thin taillights, and strong horizontals on the bumper that emphasize width.

2024 Buick Encore GX spy photos reveal Wildcat-based design

Thu, Dec 8 2022

After the reveal of the Buick Wildcat concept car, the company made it clear the styling would appear on many upcoming cars. We've seen it on the recently revealed Envista for China and the U.S., and it will appear on the first Electra electric SUV. But apparently the design language will be adapted to current Buick models, too, as evidenced by the spy photos of the new Encore GX shown above. This is clearly a refreshed Encore GX, as it's mostly the same from the A-pillars back. But the whole front end has been given a radical makeover with the Wildcat's basic looks. There's one large grille placed low in the fascia with horizontal slats. It has a pointy nose and angry headlights. It's a much more aggressive design compared to the borderline cute look of the current Encore GX. The only other significant change to the Encore GX, at least from the outside, is the use of the new Buick badge. It has the three new shields placed at the same height and without the circle. At the back, the word "BUICK" is spelled out in chrome lettering below the new badge. Since this car is completely uncovered and in production-ready guise, we're betting the refreshed Encore GX will launch sometime next year as a 2024 model. Being a refresh, it will likely have the same turbo 1.2- and 1.3-liter three-cylinder engines with front- or all-wheel drive and either a CVT or nine-speed automatic transmissions.

2024 Buick Encore GX Cupholder Mega Test: Will the Nalgene bottle fit?

Tue, May 30 2023

I recently reviewed the 2024 Buick Encore GX in its new Avenir trim, appreciating the updates from its mid-cycle refresh and assessing its comfortable driving style. What I didn't dive into, however, were the cupholders. Specifically, I wanted to know if it could accommodate in a convenient location what is my favorite hydration facilitator, a 32-ounce Nalgene water bottle. This, like other oversized water bottles, often can't find a cupholder that will fit it. Its a particularly American problem (we're more obsessed with cupholders than other markets), so can this American budget-luxury crossover satisfy my own obsession with this big, dumb bottle? Let's find out. Ideally, we could put it in the front cupholders. Few vehicles' cupholders are big enough, though, with the Chrysler Pacifica, Lexus GX and Toyota 4Runner being notable exceptions. We can't add the Encore to that list, unfortunately. The cupholders are far too small. Usually, the second best option, if possible, is to put it in the front door pocket. Voila! It fits. No Nalgene rolling around on the front passenger seat in this Buick. But what about in back? The center armrest in the Encore GX is a fine place to rest one's elbow, but what about a big-ass bottle of water? Alas, the rear cupholders are equally dinky as the ones up front, which is often the case. The last-gen Toyota Tundra was an exception, where the rear cupholders were bigger than those up front which is super weird to me. I'mm looking forward to see what's what with the new Tundra. The rear door pockets are much smaller than those up front. This does not look promising. It's just big enough that I can wedge the bottom of the bottle inside, but not big enough to keep it there when the car is in motion. Sorry backseaters, you'd better settle for your lesser bottles, suckers. I had almost overlooked this little cubby in between the front cupholders and center console armrest. It's an odd shape, but with some luck, the Nalgene will fit. That's the ticket! This is even better than putting it in the door. It's not the most secure fit, but it's not so huge a space that the bottle knocks around and falls over with every input to the steering wheel or pedals. This ended up being where I put the Nalgene every time I drove the Encore GX, and, subsequently, I remained content and adequately hydrated. And the cupholders remained open for alternative beverages. Interested in more than just the cupholders?
