Remarketing manager Jon Pollock said Nissan was always looking to develop and exploit new routes to market.
"Dealers are still our primary route, accounting for more than 95% of stock," he said. "They are also the best option financially, but Auto Online offers another string to the bow and a chance to build up a different client base with a wider trade audience.
"This isn't necessarily a market that we can tap into - we don't have a database of these people."
A mix of older stock, plus some younger models, will be put on the site, which will appeal to independent traders. "Our dealer network will still get the first crack of the whip," said Mr Pollock.
