Are there places of interest for someone who loves cars in and around Berlin?

Question

He's particularly interested in modern cars and models (Citroen, Fiat)

Answer 1

I'm sure there are, but Berlin is known for so many other things. The Air Museum comes to mind.

Answer 2

Scheeesh...of all the great car cities in Germany I just wonder why you picked Berlin...Munich and Stuttgart have huge museums.

Answer 3

There are a lot of car showrooms at the area around/at Friedrichstrasse and Unter Den Linden.

Ferrari, Opel, Peugeot, VW (plus Bentley), Mini, Audi and others have their showrooms there, which are really cool. Normally they present a variety of new and old cars and some really great prototypes. BMW has its flagship store at Kurfürstendamm, Mercedes is located in a big building near S-Bahn station Tiergarten: http://www.mercedes-welt.de/en/flash.htm...

The Deutsches Technikmuseum is also very interesting for technic-lovers.
