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.

Fullsize GM SUVs have a problem that's making owners sick

Some fullsize SUV owners are getting sick, thanks to a buffeting and vibration problem in 2015 model year examples of the Chevy Tahoe and Suburban, Cadillac Escalade, and GMC Yukon. According to owners' complaints to the National Highway Traffic Safety Administration, the issue can vary from an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. General Motors is aware of the complaints, but the fix isn't so simple. According to spokesperson Tom Wilkinson to Autoblog, the company "has been tracking this issue for a while." The problem has a fairly low incidence rate, but when it does occur the issue can be "uncomfortable and annoying for owners." There's no precise cause for the issue, Wilkinson claims, and in some cases, simply balancing the tires or changing the door seals can make it go away. However, not all of the fixes are so simple. AutoGuide dug deep into the problem and discovered a GM preliminary information bulletin that advised dealers to remove the headliner and to check the roof's bonds to the bows that go across the vehicle. However, that document included a note that the solution might not entirely eliminate things. According to AutoGuide, adding Dynamat insulation to the roof sometimes helped the problem. A GM spokesperson also told AutoGuide the company fixed the problem at the end of the 2015 model year, and didn't go into any more detail. This roof issue seems linked to some of the worst droning in these SUVs. According to one complaint from a 2015 Suburban owner to NHTSA: "Roof will not remain attached to the roof bows. This causes the buffeting similar to a window being down when all are up. The results span from annoying to painful." A 2015 Yukon owner claims to have another alleged cause for the problem in a NHTSA complaint from February 2015. This person brought their SUV to the dealer seven times over the course of four weeks for vibrations. The dealer replaced the driveshaft, suspension components, and more, but nothing worked. According to an engineer to the service adviser: "In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board." Wilkinson told Autoblog that GM is working with customers on an individual basis to rectify things. Since these are newer vehicles, dealers should also fix the problem under warranty.

Cadillac CTS Vsport laps the N"urburgring in 8:14.10 [w/video]

You don't have to be German to test your car at the Nürburging. You just have to be serious about beating the Germans on their own home turf. That's why Nissan tests its GT-R at the Nordschleife to challenge the Porsche 911, and why Cadillac - which is no less serious about putting up a fight to German performance sedans - has returned to the 'Ring once again with its latest.
This time it's the turn of the new CTS Vsport, the sportier version of Cadillac's new mid-range sedan that aims to bridge the gap until the arrival of the next CTS-V. So how'd it fare? At the end of what we're sure was an exhaustive test session, the new CTS Vsport clocked a time of 8:14.10.
To put that into context, General Motors points out that the time places the new sedan six seconds ahead of the first-gen CTS-V, whose 400-horsepower V8 engine was actually less potent than the Vsport's new 410hp 3.6-liter twin-turbo V6. That's still a good fifteen seconds slower than the outgoing CTS-V that clocked a 7:59 in 2009 with its 556hp supercharged V8, but only a second behind the E60-generation BMW M5 with its high-revving 500hp V10.
