Great, next time i go to Stuttgart i am hoping to go to the Porsche Museum instead. I believe that a new one is currently being designed and built (correct??) so i would like to see this one aswell. I have also in the past seen the BMW museum! I really liked Stuttgart as a city itself, really nice, great features and architecture. Very cosmopolitan! I love German cities like this, maybe one day i might move to Germany and live there!!!
I've been to the Porsche museum. It's not really a museum. I'm saddened that Porsche isn't really showcasing their glorious racing history. Instead, they have a little hallway big enough to fit two cars on each side and that's their "museum".
Here's my trip to the BMW Museum below.

Germany is nice, especially Bavaria where I live. I also used to study in the UK. Very nice country you have there. I'd love to go back but life is so expensive over there.
