MENLO PARK, CA – ATC-Onlane, Inc., an online auction company for automotive dealers to buy and sell wholesale vehicles, has added new consignors, including Audi Financial Services, Automotive Resources International (ARI), Mike Albert Leasing, and Vanguard Car Rental USA, Inc. They will make use of ATC Open to offer their inventory to a nationwide audience of dealers. The company also announced a new auction extension feature that keeps vehicles on the block for a longer period of time when there is a bid placed within the last five minutes of the auction close. The new auction extension feature on ATC Open was designed to provide buyers with experiences similar to those in the physical lanes. Now, a buyer can place a bid within the last five minutes of the auction’s originally scheduled end time. The vehicle will then remain on the block for another 60 minutes, as long as there is active bidding every five minutes, before the auction will officially close.
