In what will be its second auction this year sporting classic automobiles rather than earthmoving machinery, IronPlanet has joined forces with Auctions America to offer online bidding April 1-3.

Star attractions at the upcoming Fort Lauderdale, Fla., auction will include an extremely rare 1948 Tucker 48—one of only 51 examples and expected to fetch up to $1.25 million, as well as a 1981 BMW M1, which could receive a hammer price as much as $600,000. Bidders are asked to pay $100 to register as well as a 10% buyer’s premium for winning bids.

Backed by Accel Partners, Kleiner Perkins Caufield & Byers, Caterpillar and Volvo, IronPlanet typically offers construction and other industrial equipment auctions throughout the year. In February, the company began expanding its portfolio into classic cars by partnering with Leake Auction Co. for a three-day event in Oklahoma City.

IronPlanet helped Leake expand marketing and digital sales to its construction and other equipment customers, which includes 1.4 million global registered users. Among the featured items seen at the February 19-21 auction was a 1967 Chevrolet Corvette coupe painted in Goodwood Green and white interior, which sold for $157,500.

The Fort Lauderdale auction will feature more than 450 automobiles. “We are looking forward to leveraging our online marketplace technology and digital marketing experience to further promote this collection,” says Gregory J. Owens, chairman and CEO of IronPlanet.
