How many Citroën 2CV models have been produced?

Explanation

Citroën 2CV (deux chevaux, French for two horsepower) was a simple passenger car from Citroën, sold from 1948 until 1990, when the production was stopped. 2CV is known for its characteristic shape and simplicity, but also for its very limited horsepower - the top model only had 32 hp. The car is known for being sturdy in all terrain. One of the most famous 'tests' was that the car should be able to drive through a field with a tray of eggs without any of them breaking. All in all, 3,867,932 2CVs were produced.
