The Spanish car maker, most famed for its small, stylish cars such as the Ibiza supermini and Leon hatchback, sold 3,000 cars in June alone, 32 per cent up on June 2010.
It has now expanded its share of the UK market to 1.7 per cent, an all time high for the manufacturer and a figure which highlights its push to increase its presence in the UK.
Seat UK Head of Operations, Richard Harrison, says the numbers ‘speak for themselves’ and show the brand’s plan for growth is on track in the UK.
He added: "Our dealer network has experienced record levels of interest and sales across the entire range of stylish new Seats, and it’s clear that the expanded modern range of cars we offer is connecting with buyers like never before."
Seat currently boasts the youngest average customer age in the UK, a testament to its youthful, sporty cars. This is none more evident than in the likes of the Seat Leon Cupra R and Seat Ibiza Bocanegra hot hatches.
The most popular car in the Seat Ibiza with more than 10,000 models sold in 2011 so far. Available in SC (sport coupe), hatchback and ST versions, the Ibiza starts from £10,000.
The Seat Leon five-door hatchback has also attracted interest in 2011 from buyers with over 5,000 people choosing the model.
Other models such as the Exeo saloon and new seven-seat Seat Alhambra also sold strongly to give the brand its best sixth months in the UK ever.
The success of the Spanish car maker comes amid a steady decline in UK new car sales as a whole and a 6.2 per cent dip in June 2011 compared to the same month last year.
