At some point in time, the Shelby Mustang GT500 Convertible will be a collector's piece that will likely cost a pretty penny, especially if it's the last ever produced.

But that's well into the future, probably decades away from now.

At the present time, though, the final 2014 Shelby Mustang GT500 Convertible still commanded plenty of attention at the recent Hot August Nights Auction presented by Barrett-Jackson. The whole auction was a resounding success with total sales numbers eclipsing $14.2 million.

As expected, the biggest contributor to that total was the final 2014 Shelby Mustang GT500 Convertible, accounting for $500,000 when the hammer fell on its auction. That may seem like a steep price to pay for a car that routinely costs at a little over a tenth of the price that this unique model fetched in the auction.

That being said, nobody else can lay claim to owning the last ever produced Shelby Mustang GT500 and besides, as the last of the lot, the winning owner now has the opportunity to completely customize the car to its full bloom.

At some point in the future, this model could very well be worth way more than the half-a-million the winning bidder paid for the right to own it.

2013 Shelby Mustang GT500 Convertible

The GT500 Convertible -- just like its coupe brother -- is currently one of the most powerful models ever offered by Ford. It is powered by 5.8-liter V-8 engine that delivers a total of 662 horsepower and 631 pound-feet of torque.

The GT500 can hit a top speed of 190 mph and goes from 0 to 60 mph in just 4 seconds.

On the U.S. market, the GT500 Convertible is priced from $59,800.

With the model now on its proverbial last legs, it'll be extremely difficult for a lot of people to let go of the heritage and legacy of this unique muscle car. But alas, there are always goodbyes in the auto industry, even for cars that have the cache of the Shelby and Mustang names attached to it.
