The four-millionth Fiesta has been handed over to Michelle Wardale – who had previously owned three Ford models – by dealer Benfield Sunderland.
The Fiesta has led the small car segment in the UK for 27 of its 37 years and has remained Britain’s overall best-seller since 2009, when it overtook the Ford Focus.
Wardale said: ‘When I was told I’d chosen the four millionth Fiesta I was totally shocked – it’s not the sort of thing that normally happens to me!’
Ford Britain chairman and managing director, Mark Ovenden, said: ‘The success of the Ford Fiesta means a great deal to the whole Ford team. This car combines style, value, driving dynamics and remarkable technologies such as the award-winning EcoBoost engine and Ford MyKey.
‘Today it outsells its nearest retail competitor by more than two to one – and that really tells the story of this extraordinary car.’
