The Simulcast bids at its Leeds auction centre topped £580,000 on the day, with 39 of the 140 vehicles – comprising Mercedes-Benz and smart – being secured by online bidders.
A total of 47 Simulcast buyers were logged on throughout the sale, with more than 60 buyers on site for the physical auction.
Buyers in the auction hall were able to see the internet bids as they came in on large plasma screens, which flashed red every time an e-bid was placed.
Online bidders can watch live images of the auction hall and listen to the auctioneer's commentary via their PCs.
Ruth Justice, Manheim Auctions' national account manager, manufacturers, said: 'The bidding generated by the physical and virtual bids created a lively atmosphere.'
Mercedes-Benz wholesale sales consultant Paul Margery said: 'There was a buzz from physical buyers in the auction hall, but just as important was the strong demand from dealers who couldn't attend the sale.'
