Speed Digital announced it will partner with HemmingsPRO Auctions to host a battle more than 50 years in the making: Mustangs versus Camaros. 

On May 26, the new partners will bring collectors and enthusiasts a Mustangs versus Camaros sale, the first of a series of monthly themed, timed online auctions.

This event will help settle the long-standing rivalry between the two sporsts car brands and determine which American classic is truly most popular, Speed Digital said. 

"We look forward to bringing this unique auction format to millions of Mustang and Camaro fans," Speed Digital president Neil Pitt said in a news release. "It will be exciting to see which fan base has a stronger showing. Will a Mustang or Camaro bring in the highest winning bid? Will more Mustangs find new homes or will it be Camaros? Only time will tell, but it will be fun to watch it all unfold on May 26."  

Mustangs and Camaros from 1964 to 2017 will be included in the auction and all inventory will be provided by dealers within Speed Digital's Dealer Accelerate network.

Interested buyers can currently bid at hemmings.speeddigital.com. The timed online auction will close on the night of May 26.

During the live auction, a 2017 Petty's Garage King Premier Edition Mustang powered by a 5.0L V-8 engine producing 825 HP will be auctioned off at 7 p.m.

The customized car signed by Richard Petty himself comes in the Petty's Garage signature limited "ghost series" black and silver paint scheme. According to Speed Digital, the proceeds from the sale of the car will go to charity.

"The Petty's Garage Mustang won't be the only vehicle drawing interest during the Mustangs vs. Camaros online auction. You would be hard-pressed to find more premier Mustangs and Camaros in another auction," Speed Digital added. "Two of the most sought-after vehicles that will have bidders reaching for their wallets include a 1969 Ford Mustang estimated to go between $236,000 and $355,000 at the auction and a 2015 Chevrolet Camaro COPO."

Other sought after cars include the 1968 Shelby GT500, the 1970 Ford Mustang Boss 302 and the 1969 Chevrolet Camaro SS, which are estimated to go for $133,000 to $187,000, $99,000 to $134,000 and $90,000 to $122,000, respectively, according to Speed Digital.
