Seat sales in 2007 increased by 5.9 per cent on the previous year, according to figures produced by the Society of Motor Manufacturers and Traders.
The statistics show that the total number of Seat registrations for the year was 34,790, compared to 32,839 in 2006.
Following the release of the figures, Seat has said that it wants to continue breaking sales records in the coming year.
Peter Wyhinny, director of Seat UK, remarked: "We are, very clearly, a brand which is continuing on the up. In fact total sales last year were just shy of our all-time UK record.
"These most recent sales figures prove Seat offers cars that British buyers are crying out for."
He added that the company is placed in an ideal situation to achieve record registrations in the year ahead.
Last week, Seat’s Martorell plant in Spain, which opened in 1993, produced its six-millionth unit. The car in question, a white Ibiza Ecomotive, is the most-environmentally-friendly vehicle the company has ever manufactured.
