Acording to figures produced by the Society of Motor Traders and Manufacturers, the car's 2017 sales left it 104 units short of the 2016 tally.
The car, a Haldex driveline-equipped version of the Leon ST estate that can send up to 50% of torque to its rear wheels, is the most rugged mode in the Leon line-up. It offers soft-roader capabilities along with a more forgiving ride.
A Seat spokesman told Autocar that the move was also partly driven by the removal of heated leather seats from the Leon range at the last update. The X-Perience, which came exclusively with a 2.0 TDI engine and cost from £28,975, had been offered with these as standard.
The X-Perience's low demand illustrates a growing decline for rugged estates in the UK market. The similarly-specced Volkswagen Golf Alltrack sold in just 72 units, a drop of 290 units on 2016, while the Skoda Octavia Scout sold in 825 units for the nine months it was on sale in 2017.
