SEAT shares its engines, gearboxes, and platforms with VW, Skoda, and Audi — but at lower prices. The Leon is one of the best-value performance hatches available used. Cupra is the performance sub-brand that now stands alone. DSG dry clutch issues on 1.2/1.4 TSI, 1.4 TSI timing chain on early Mk3 Leon, and DSG fluid neglect are the watchpoints shared with the wider VW Group.
