This year marks the 50th anniversary for Shelby American, the company behind the sporty performance cars that once stood alone but are now tightly entwined with Ford Mustang. To celebrate the milestone, Shelby had a special showcase set up just outside the entrance to the New York International Auto Show. Nearly a dozen customized Mustang Shelby vehicles were on display in a roped-off section, but one car stood out from the crowd of mostly-new vehicles. The very first Shelby ever built stood on a raised platform on the outer edge, making it the first vehicle visitors saw as they entered the Javits Center in New York City.

The Shelby, built in 1962, belongs to company founder Carroll Shelby and made its first world debut at the very same auto show half a century ago. The vehicle appeared to have been taken care of over the years, but signs of wear and tear were apparent in the torn leather seats and worn shifter. AutoBlog estimates the value of the sporty vehicle to be around $20 million, but Shelby has no plans of selling.

"I heard someone once offered him $25 million for it, but he turned it down," a Ford spokesperson explained at the Auto Show.

The anniversary was also marked by the debut of the newest Shelby 1,000, based on a Mustang GT500. The street-legal version of this supercar offers 950 hp, and the track-only model is even more powerful with 1,100 hp. The latest Shelby is the most powerful sports car ever made by Shelby or Ford, Torque News reports.

However, with a price tag starting around $150,000, this car is not for everyone. Those looking for used cars in NJ, whether they want to find a powerful Mustang or something smaller and more fuel-efficient, can head to New Jersey State Auto Auction. The dealer has a wide selection of makes and models at affordable prices.
