Next weekend, the Barrett-Jackson auction returns to Sin City for its annual Las Vegas auction event. For car collectors, enthusiasts, and gamblers, this is the place to be with over 500 cars, ranging from classics to concepts, up for auction. As always, the Ford Mustang is well represented in this lot, though this year Barrett-Jackson has an especially large collection of valuable Shelby vehicles up for grabs as well.

These cars run the whole gamut of Shelby vehicles, including Cobras, GT500’s, and GT350s. We’ve picked out some of our favorite Shelby vehicles from the lineup to preview for you, so you can sit back and drool with the rest of us as these cars cross the block next week.

First up is Lot #6600, a truly stunning and rare street-legal race car, a Shelby GT500 SE Super Snake “continuation car.” This “1967” Shelby was part of a brief series of continuation cars built by Shelby in the years after the muscle car wars. This particular car features a treasure trove of modernized options in a classic body.

This includes a 800 horsepower 482 cubic-inch all-aluminum V8, a 5-speed Tremec TKO transmission, air conditioning and a track-ready suspension. Also on board is a DVD player, a 700 watt Clarion sound system, and a plush, well-appointed interior. Expect this car to go for big bucks.

Then there is Lot #674, a 1970 Shelby GT500. With a Ram Air 428 Super Cobra Jet big block V8 backed by a 4-speed manual transmission, you wouldn’t expect a fully-functional smog system on a car like this. But it has it! This car was originally shipped to Canada, and its unique option packages make it quite rare in the grand scheme of things. Rare, but hardly the most desirable Shelby of the auction.

Instead, that title may apply to lot #669, a fully rotisserie-restored 1967 Shelby GT500 fastback painted in the classic Wimbledon White with Guardsman Blue stripes. With a dual-carbureted 428 V8 under the hood, this is perhaps the cleanest car of the lot. It’s prime example of a collector car, and we have no doubt that is exactly where it’ll end up.

Less certain is the fate of Lot #665.1, a 1966 Shelby GT350 with a 400 horsepower 289 V8 engine. This car has been built for the track, and is currently track legal for any vintage road racing event in either the U.S. or Canada. While our gut instinct says that this car will end up being driven, and driven hard, there is always the off chance that some collector decides “Hey, that would look good in my garage.” Regardless, it’s a pretty sweet ride, raced, cruised, and stored away.

Lot #630 also has a lot of collector car potential, being a 2008 GT500 KR edition with less than 400 miles on the odometer. Shelby made a triumphant return in 2005 with the GT500, though chief among the many Shelby variants is the the KR edition. The 5.4 liter V8 cranks out 540 horsepower, and with every option included, this car cost over $80,000 brand new. Has that value gone up? We’ll have to watch the auction to see.

Finally, there is Lot #637, a 2007 Shelby GT500 Super Snake, a car whose main claim to fame is being used as a Shelby tester. Of the just 63 miles on the odometer, 46 are documented as a Shelby test car. This vehicle is as new as it gets, and served as a testbed for other Shelby Super Snakes to boot. On top of all that, this fully-loaded Super Snake boasts a 630 horsepower 5.4 liter V8 engine, not that it is likely to ever get driven. This is a modern collector car, through and through, and should draw an impressive price at auction.

Yet the question we find ourselves asking…which of these Shelbys will draw the top bid? It could be just about any of them, because when it comes to auctions, all bets are off. Still, if you had to put money on the top selling car…which Shelby would it be?
