More on the SEAT Leon

How this is measured. 2021 refers to the registration year. Figures are seven-day trailing medians over days that passed our data-quality checks, covering cars with recorded mileage above 1,000.

Comparisons between years describe different cars on sale today — a 2021 car next to a newer one — not one car losing value over time.

Market data through 10 August 2026, based on 7 days of measurements.
