If you had to have a guess, which car would you say sold more than any other in the history of motoring?
If you're thinking the Toyota Corolla, which has sold over 30 million units, then you'd be wrong.
The reason the Corolla is disqualified is that even though it has been an extremely popular seller across the globe these sales of 'Corollas' include several entirely different models down the years and as these are, essentially, different cars that only share a model name they are not counted here.
If you're second guess was the Volkswagen Beetle, then congratulations - you're right.
Between 1939 and 2003, when production of the original beetle finally ceased, 21 million Beetles were built.
Second biggest seller is the Fiat 124 with 15 million built including badge engineered versions sold under Seat, Lada as well as Turkish and Indian brands.
The Fiat 124 is actually still in production by Lada in Russia, where they still sell 200,000 units per year.
The third most popular car in automotive history is the Ford Model T. For what is regarded as 'the original car' (on sale since 1908) and the vehicle which made private transport a reality it was the world's biggest seller until the Volkswagen Beetle passed it out in 1973.
The Fiat Uno is the fourth best selling car with 8.3 million having been sold since its introduction in 1983. The Renault 4, which was inspired by the quirky little Citroen 2CV, sold a cool eight million vehicles.
Volkswagen's Golf Mk1 and MkII, respectively, sit at numbers six and seven respectively.
The original Golf was introduced in 1974 and is still being built in South Africa. To date, 6.9 million have been manufactured.
The Peugeot 206 is one of the three cars in the list which can still be bought. Over 5.5 million have been built and the 206 is still manufactured in Peugeot factories in Argentina, France, Brazil and Iran.
At number nine, the second Renault in the list is the Renault 5 - with slightly fewer than five and a half million sold between 1972 and 1983.
Completing the top ten is the Mini. With 5.3 million sold world-wide this iconic little car just pips the Peugeot 205 to the top ten list. The Mini was in production for 41 years - between 1959 and 2000.
