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.

Buick envisioning a refreshed Envision crossover

Tue, Sep 19 2017

Buick's first fully Chinese-built vehicle in the U.S., the Envision crossover, is now getting its very first refresh. Cars grow up so fast, don't they? There's no time to be wistful, though, so we need to take a look at this prototype. It looks like the Envision refresh is going to be very mild and focuses on strengthening the family resemblance between it and other Buicks. The waterfall grille now has a horizontal bar that intersects with the badge, as seen on every new and updated Buick since the latest LaCrosse. And although that badge is covered, we wouldn't be surprised if it changes from the all-silver design to the classic red, white and blue version that was reintroduced on the LaCrosse. The lower grilles have been changed, too. The outboard grilles that house the fog lights look smaller and less pronounced than on the current model, and the center piece appears to be thinner and wider. It also more naturally merges into the plastic air dam. The tail of this Envision, though more heavily camouflaged, also shows some minor updates. The most significant of them are the new taillights. They appear to have a similar boomerang shape as those on the LaCrosse, a distinct change from the ovular units of the current model. The lower edge of the bumper seems to have more of a faux diffuser look, and the exhaust tips now blend into the shape of the bumper, rather than ending in simple round shapes. Since this update is clearly a mild one, we would expect to see the new Envision on sale sometime next year, probably as a 2019 model. It will join a rather fresh Buick lineup alongside the new Regal and Enclave.

Buick Encore takes a hit of Mokka to tackle Dakar

Wed, 03 Sep 2014

There are many vehicles we'd consider taking racing. Even on a cross-country rally as punishing as the Dakar. But a Buick Encore? That's not one that would enter our motorsports-based consciousness. Yet it's basically what General Motors is entering in the South American rally raid this year, and you're looking at it.
Unveiled at the Moscow Motor Show, this rally machine is based on (or at least billed as) an Opel Mokka - the name that GM's European brand applies to the vehicle Americans know as the Encore, Buick's subcompact crossover. Only it's obviously been extensively modified. It's got a ten-inch raised suspension, a 137-gallon fuel tank, carbon-fiber bodywork and... hold on, we're sure we're missing something here. Oh, right: a 6.2-liter V8 kicking out 340 horsepower and 487 pound-feet of torque to all four wheels through a six-speed sequential gearbox.
In other words, this is not the same Encore (or Mokka) you can pick up at your local Buick, Opel or Vauxhall dealership. It's not even close. It's not even recognizable as such, really. It was unveiled alongside a more sedate Opel Mokka Moscow Edition and a slew of other local debuts for the Opel brand that you can read more about in the (translated and original) Russian press release below.

How to hack a Buick Regal with CarKnow

Thu, 08 Aug 2013

If you own an Apple iPhone or Android device, perhaps you've been tempted to jailbreak or root it. This process gives you access to the the software's code, and can be used to make minor or drastic changes to its operating system. CarKnow, a company in Boston, is working applying a similar concept to the automobile.
Translogic recently took a look inside CarKnow to see just how it can tweak the computers inside a car and what sort of things can be done. As our transportation tech sister site explains, CarKnow basically created a digital duplicate of their Buick Regal in the cloud, while harvesting data generated to create custom apps and infiltrate the deepest function of their test car.
And before you freak out about people maliciously taking over your car, CarKnow's founder, Josh Siegel, stresses that it isn't quite so easy as driving up alongside someone. Take a look at the full video below to see just what it's like to jailbreak a car.
