Figures from the Society of the Irish Motor Industry have revealed that Airside Motor Park in Swords, near Dublin, was the biggest car retailer in 2010.
Airside delivered 3,360 cars to customers in 2010, which accounts for 3.7 percent of the total Irish market.
The company claims that Airside's location near Dublin airport puts it within 90 minutes' drive of more than 60 percent of Irish motorists.
The Irish car market should be buoyed by the six-month extension of the Scrappage Scheme, which the SIMI says was partly responsible for the 55 percent jump in Irish sales in 2010.
