2017 SEAT Leon Cupra 300 DSG | Stage 1 | Extensive Service History For sale is my 2017 SEAT Leon Cupra 300 DSG, featuring the 2.0 TSI turbocharged petrol engine and 5-door hatchback body style. The car benefits from an extensive service history, including a recent full service carried out by a SEAT main dealership at 100,000 miles, alongside documented DSG gearbox and differential servicing.

There is also a small crease in the Maxton front splitter, and the alloy wheels would benefit from refurbishment due to some peeling paintwork. These imperfections have been reflected in the asking price and are shown in the photographs. The Cupra 300 offers an excellent balance of performance, handling and everyday practicality. The Stage 1 remap enhances the already impressive performance of the 2.0 TSI engine, while the uprated brakes and resonator delete complement the overall driving experience. With 100,300 miles and a substantial maintenance history, including recent main dealer servicing, this is a great opportunity to own a well-equipped and extensively maintained performance hatchback.
