11 vehicles from Barrett-Jackson Las Vegas worth watching

This weekend will see the world's collector car crowds descend on Las Vegas, NV for one of the biggest shows on Barrett-Jackson's popular auction circuit. There are hundreds of vehicles up for bidding, ranging from a brand-new Lamborghini Aventador to a spattering of Art Deco classics and a huge swath of classic muscle cars.
While it's virtually impossible to assemble an inarguable list of the best cars coming during the three-day, 700-plus vehicle auction, we've sifted through the listings for this year's show - it was a tough assignment, we promise - and assembled a list of what we think will be some of the most interesting lots. We'll admit, it's a bit heavy on American iron, but if you browse BJ's listings, you'll come to a similar conclusion. Still, scroll down for our list of what we think will be the most interesting vehicles at the upcoming auction.

Ghostbusters' Ecto-1 detailed in behind-the-scenes video

The Ghostbusters reboot is coming, ready or not. And along with a gender swap between the 'busters and their secretary, the team's trusty chariot, Ecto-1, is getting a refresh. It's still a specialized Cadillac, but that's where the similarities end, judging by the new featurette you see above. Instead of a 1959 Cadillac Miller-Meteor Ambulance, 2016's Ecto-1 is a 1982 Cadillac Deville. And instead of being built to keep people from dying, the new car is meant to transport the dead. Yep, it's a hearse. It's hard not to find some kind of hidden meaning there, but this video doesn't mention it. What we have learned here is that the way the new Ghostbusters acquire their vehicle is a little bit different than it was in the original film. In the 1984 version, Dr. Ray Stantz, played by Dan Aykroyd, bought the 1959 ambulance for $4,800 – the equivalent of $11,000 today – despite a litany of problems. It was clear in the film that Ecto-1 was dilapidated long before the Ghostbusters breathed life back into it. But in the new film, the team acquires Ecto-1 from the uncle of Patty Tolan – Leslie Jones' character. And based on the film featurette, it looks like it's in solid shape before the team adds its distinctive livery and logo. You can learn more about the car, see parts of the build process, and hear the cast and crew talk about it in this two-minute featurette. Ghostbusters hits theaters on July 15. Related Video:

Canada opens probe into 250,000 GM pickups, SUVs over brake performance

Transport Canada, the auto safety regulator, has opened a probe into braking issues in nearly 250,000 General Motors full-size pickups and SUVs after U.S. officials launched a similar probe last year, the agency said on its website. The U.S. National Highway Traffic Safety Administration (NHTSA) in November into 2.73 million U.S. 2014-2016 model year SUVs and pickups after receiving 487 reports of hard brake pedal effort accompanied by extended stopping distance that were attributed to deterioration of the engine-driven brake assist vacuum pump. Transport Canada's probe covers 249,700 2015 through 2017 model year vehicles including the Cadillac Escalade, Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon as well as 2014-2017 Chevrolet Silverado LD and GMC Sierra LD vehicles. The U.S. agency said it had reports of nine incidents of vehicles incurring damage as a result of colliding with another vehicle or fixed object at low speeds and reports of two injuries. NHTSA said if the pump fails to operate, the amount of brake power assist can be significantly reduced, extending vehicle stopping distance. The NHTSA sent GM an information request in a Feb. 7 letter. A GM spokesman said he had no update on the investigation. Reporting by David Shepardson; editing by Jonathan Oatis
