Our estimate draws on 6,886 BMW 3 Series adverts across the UK, adjusting for age, mileage, trim, engine and other specifications.

MOT records show an expiry date of 25 October 2026, and the latest recorded mileage is consistent with the advert. It is advertised by Hawkins Select Indian Queens in St Columb.
