Hyundai have been selling cars in the UK since 1982 and the last 10 years have been their most successful.
Hyundai have marked the occasion by running a twitter competition where entrants had the chance to win an all new Tucson SUV and to be in with a chance they had to use the hashtag #M1LLION and tweet Hyundai to say who their 1 in a million is.
The competition has now closed but Hyundai are yet to announce the winner so keep an eye on their twitter page
Hyundai said that the best advertisement is seeing their cars on the road, especially with that many out there.
This news comes just as Hyundai announced that the Tucson has been their fastest selling car and with the new Ioniq's release due later this month the future is looking good for Hyundai!
