1987 Buick Grand National was made to be Kevin Hart's 'Dark Knight'

The Meguiar's booth at the SEMA show isn't the only place comedian and actor Kevin Hart is combining cars and cinema, his "Michael Myers" 1969 Plymouth Road Runner brooding in the car care products pen, while his SpeedKore "Hellraiser" 1970 Dodge Charger also menaces. Hart bought a 1987 Buick GNX last year and put it on Instagram with the caption, "Sundays are perfect for old school drives…. If you know you know." Looks like old G-Bodies are perfect for restomod builds, too, which we all already knew, but this car isn't the GNX that featured on social media. This is the 1987 Buick Grand National, one step below the GNX and half the price at the time. It's nicknamed "Dark Knight" and it's one of the stars of the Magnaflow exhaust booth at SEMA. Going back to work with regular collaborators Dave Salvaggio of Salvaggio Design and Sean Smith, of course there's a lot involved in the overhaul. Still, we appreciate how the team stayed true to the ethos of the Grand National in ways that made the build more complicated than it already was. Take the engine. The original came with a 3.8-liter V6 wearing a single turbocharger to register an official output of 245 horsepower and 355 pound-feet of torque compared to the GNX's 276 hp and 320 lb-ft. Instead of swapping it for a V8, it's been replaced with the 3.6-liter twin-turbo V6 from the Cadillac CT4-V Blackwing. And instead of leaving both turbos on, the engine junkies plumbed a single turbo in a layout recalling the 1987 engine even as it cleans up the original Chutes 'n' Ladders mess of tubes. We didn't get an output rating for the setup. The Cadillac's twin-turbo mill makes 472 hp and 445 lb-ft. in the CT4-V Blackwing. We would bet Dark Knight's engine's pretty close to that with the single large turbo at the prow, plenty of juice for a car weighing 3,545 pounds. Exterior upgrades include a custom front fascia with a carbon fiber hood and splitter. The interior shows the same tasteful restraint, polished design and nicer materials draped over the stock 1980s layout. That shifter controls GM's 8L90 eight-speed automatic instead of the original four-speed auto.  Elsewhere, Salvaggio did the same here as with the Michael Myers Road Runner, creating a custom frame to increase rigidity and get the car closer to the ground on its 19-inch HRE wheels in the Buick's original weave look.

Buick Encore blitzes first-year sales predictions

With its first full year of sales in the bag, it's safe to say that Buick has a hit on its hands with the Encore. US buyers have snatched up 31,046 of the small, premium crossovers since the Encore went on sale in January of 2013, while 97,311 were sold globally (not counting its counterparts from Opel and Vauxhall).
While we liked the Encore when we first drove it, we'll admit, we weren't sure how the tiny CUV would do. In fact, the first thing Executive Editor Chris Paukert wrote about the Encore was, "We admit it. We have no earthly idea how this whole thing is going to shake out." But it's done well, and has been subject to heavy demand over the past year, blowing away the estimates of analysts, who, according to an August story from Automotive News, projected no more than 18,500 units would be sold in 2013.
"Right out of the gate, demand for the Encore was high," Tony DiSalle, vice president of Buick marketing said in a statement. "It accounted for most of the segment's growth last year and that's because it offers the right safety, technology and features in the right-sized vehicle for many customers."

GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.
