Thousands of cars crossed the stage at this year’s Barrett-Jackson Northeast auction, which took place in Uncasville, Connecticut, as in previous years. Of those cars, however, were three special, rare, or otherwise unique classic Mustangs which we’ve decided to highlight. See, classic Mustangs are sort of like fine wine – they age quite nicely with time, and in our opinion, really are a timeless look.

Whether you’re a fan of the coupe, Sportsroof, or Fastback models, we think these three Mustangs – which auctioned for more than $750,000 accumulatively — might just pique your interest. We’ll start with the most profitable Mustang auctioned off and work our way down. Not surprisingly, each one of these Mustangs yielded a price tag of more than six figures last weekend at the Northeast event…

Though not highlighted as one of our Top 10 Colors That Should Return, your author admittedly is a huge fan of the finish on this ’69 Boss 429, which is the “mostly all-original” Royal Maroon paint. Auctioned for more than $407,000, this Boss 429 only had approximately 2,000 miles on its odometer at the time of the auction, and is powered by the original 429-cubic-inch V8, paired to its original four-speed manual transmission. According to the listing, it looks as if nothing on this Boss was modified.

“Shelby Designed, Cobra Bred, Ford Powered and Rented Exclusively by Hertz.” That was the phrase used to describe the 1966 Ford Mustang Shelby GT350-H, and this classic Rent-A-Racer Mustang is one of only 999 built for that year. It’s also one of only 59 finished in Ivy Green, and this particular Shelby was ordered with the Hertz special wheels, radio and brake booster available at the time.

According to the original listing, “The last owner, in Wisconsin, purchased the car in 2004 as a survivor. He had the car completely restored in 2010, by well-known Shelby restorer and owner of Shelby Parts and Restoration, Jim Cowles. Most of the parts that were replaced during the restoration were Ford NOS or OEM. The car retains almost all of its original sheet metal and has a framed fiberglass hood.”

Often referred to as one of the most iconic movie cars (and Mustangs for that matter) is this beauty, a recreation of the 2000 movie Gone In 60 Seconds movie car, a 1967 Ford Mustang Shelby GT500. Known as Eleanor both in the movie and amongst enthusiasts, this archetypal Mustang started as an original S-code 390-cubic-inch big-block-powered GT Fastback and concluded its build as a zero-mile restoration, incorporating an Eleanor body courtesy of ’Stang-Aholics.

It is listed in the Eleanor World Registry, and features “a correct Pepper Gray Metallic, two-stage exterior paint with rich, black GT body-stripes, GT500E rocker stripes, and GT500 badging throughout.” Moreover, the rebuilt, 390-cubic-inch V8 incorporates GT cylinder heads, GT exhaust manifolds and a GT intake manifold, all buttoned up to a four-speed Toploader manual transmission.
