Recalls, other countries and running costs, side by side
DVSA lists 58 recall campaigns matched to the Vauxhall Corsa and 30 to the Volkswagen Polo; more campaigns do not by themselves mean a less reliable car. Abroad, compare each model with that country's own average, because pass rates do not carry across rulebooks. Repair bills are catalogue estimates, not quotes.
