Volkswagen History.

 

The Volkswagen type 1 is perhaps most known as the "beetle" or the "bug". The production of the beetle started in 1938 whith the first prototype. The purpose whith this car was that it would be so cheap that common family´s could afford it. Although it was rather inexpensive, it was a very reliable car. The beetle is the most selling car in the world whith over 20 million cars sold. It is still being produced in Mexico. The beetle has changed a lot during the year. Below you can see how the changes was made from year to year.
