Last-ever Buick Grand National heads to Barrett-Jackson auction

This 1987 Buick Grand National brought the curtains down on a heap of General Motors history. When this black beauty rolled down the line at 5 p.m. on December 11, 1987, it represented the end of manufacturing at GM's Pontiac Assembly Plant after 60 years building cars. This was the last car to sit on GM's G-Body platform, having supported legendary names like Monte Carlo, Cutlass Supreme, and Regal. And this was the last-ever Buick Grand National, a big coupe that in just five years on the market had helped make the Buick Regal lineup an object of sincere lust among enthusiasts. Powered by a 3.8-liter turbocharged and intercooled 3.8-liter V6, the engine made 245 horsepower and 355 pound-feet of torque. The only car above it in the lineup was the exceptionally rare GNX, which made 276 hp and 360 lb-ft. The Buick Grand National is headed to the Barrett-Jackson auction block in Scottsdale next month.    Louisiana resident Bob Colvin bought this car from the factory. The Drive spoke to Colvin, who explained that then-GM President Roger Smith told him he could have the penultimate Grand National, but Buick planned to put the last car on display. When Colvin arrived at the plant, though, Colvin said the plant manager told him, "I'm running this plant and you've gone through the effort to be here. It will be a real celebration," and got him the last car made. As proof, a GM film crew followed the car down the line, plant workers and two GM execs signed various parts of the engine, including current GM President Mark Reuss. The car comes with all of the autographs and signage the autoworkers created to go with the car, as well as the original window sticker. Colvin and his wife built an addition onto their house to display the car. Save for a trip to the Buick Centennial Celebration in 2003, the Buick has lived in its special place all its life and has just 33 miles on the odometer. Behind the new-car plastic that shrouds the interior, the only flaw appears to be a tiny crack in the steering wheel center cap where a bolt might have been overtorqued. The car is being offered with no reserve, the pre-sale estimate landing right around the $500,000 mark. That would about double recent auction sales for low-mileage GNX's this year, but there's every reason to believe this car's one-of-one place in history could get auction paddles waving. 

Trademarks indicate Buick Regal wagon could be on the way

American wagon fans have been waiting for General Motors to import a Buick-badged version of the Opel Insignia Sports Tourer since the current Insignia-based Regal hit dealers. If a new patent filing is any indication, that day could be coming soon. Then again, it might not mean anything. AutoGuide reports that Buick has filed two trademarks with the US Patent and Trademark Office for "Motor land vehicles, namely automobiles." You can see the trademarks for "Tourx" and "Regal Tourx" here and here. "Tour" smacks of wagon models, while the "x" – for all-wheel drive – makes us wonder if maybe we'll be seeing a rebadged version of the high-riding Opel Insignia Country Tourer (shown above). This isn't the first time Buick has stoked the hopes of US wagon fans, though. Earlier this year, trademarks were filed for the "Regal Sport Touring," a name that's very close to the Euro-market wagon's title. In fact, that trademark had the same description as the Tourx/Regal Tourx filings. As we've established before, automakers file trademarks all the time. It's far from a guarantee that anything will come of such trademarked names. Still, two wagon-ish filings with the USPTO from Buick in under a year makes it seem like there's at least someone at the Trishield brand that's campaigning for a long-roof Regal. Fight the good fight, friend. Related Video:

GM expands headlight recall to 180k Buicks and Pontiacs

General Motors is issuing an expanded headlight module recall to include 180,504 examples in North America of the 2005 Buick LaCrosse (2008 model year pictured above) and 2007 Pontiac Grand Prix. Specifically, the campaign affects 159,584 of them in the US and 20,920 in Canada. When the part fails, the vehicles' low beams can stop working either intermittently or permanently. "GM is unable to confirm any crashes, injuries or fatalities related to this condition," the company said in a statement, and there's currently no permanent repair for the problem. For now, dealers will replace the headlamp module with a new example of the same part. The automaker first announced this campaign in November 2014 when it affected 316,357 examples globally of the 2006-09 Buick LaCrosse; 2006-2007 Chevy TrailBlazer and TrailBlazer EXT; 2006-2007 GMC Envoy and 2006 GMC Envoy XL; 2006-2007 Buick Rainier; 2006-2008 Saab 9-7X; and 2006-08 Isuzu Ascender.
