Despite a new model on its way, the outgoing Vauxhall Corsa managed to hold onto its title as the third best-selling car in the UK last year, with 81,783 registered. A replacement means less demand for the old model which, combined with a flooded market, equals shocking depreciation. We doubt many people paid full price for a new one, though.
