CITROEN are very interresting cars. They always designed cars that were 20 years before the other.
These are considered as the classics
The TRACTION was first front wheel drive / full body (no chassis)
The 2 CV . Front wheel drive produces 40 years. Simpliest car you can design
The DS ... THE french car. Very unique in design and technology
The SM ... The most exclusive. Rare car with Maserati v6 engine ...
