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.

Ford F-150 RaptorTrax is Ken Block's ultimate snowmobile

Even when Ken Block isn't starring in the latest Gymkhana video or tearing up Global RallyCross courses, he's finding new ways to redefine "awesome" as it applies to motorsports. For evidence of this, look no further than Block's latest Monster-badged creation, the Ford F-150 RaptorTrax.
Billed as the "world's fastest snowcat," the RaptorTrax started life as a Ford F-150 SVT Raptor, and then a set of Mattracks were put in place where the truck's bead-locked wheels and meaty rubber once resided. The goal was to create a truck that made it easier - and presumably more fun - for Block and his buddies to hit the slopes on their snowboards. Aside from the obvious track upgrades, this truck also received a Whipple supercharger, full roll cage, Recaro seats, an in-bed snowboard rack, a roof basket and a rear-mounted winch - you know, just in case something or someone actually manages to get this truck stuck.
The RaptorTrax will be on display later this week at the Winter X Games in Apsen, CO, but we'll have to wait until next winter for a full Block-worthy video of the truck. A full press release from Hoonigan Racing Division is posted below, and a high-res image can be found by clicking above.

Ford cleans up painting process with cameras

Knowing how the bacon gets made rarely entices us and, in the same vein, the same usually goes for knowing about how new cars get painted. But in both instances, however, quality - or a lack thereof - is instantly obvious. In terms of the latter, Ford is showing off its new paint quality process with 3D Dirt Detection Technology to find imperfections in vehicle paint more easily and more quickly.
This process - being performed on the F-150 SVT Raptor above - uses 16 computer-controlled cameras to create a three-dimensional model (inset) of the vehicle to detect flaws in the paint including dirt particles, which can then be buffed out manually. Ford says this new technology cuts down on time spent looking for paint flaws and gives workers more time to correct those that are discovered.
Currently, Ford only uses its 3D Dirt Detection Technology system at three factories (the Dearborn, MI facility, along with those in Louisville, Kentucky and Valencia, Spain), but it will soon spread to five more plants in North America. Ford has released a video and press release for this innovative and unexpectedly interesting process, both of which are posted below.
