One of the biggest gatherings of BMW enthusiasts takes place in the United States, proving they have a closely knit and very devoted fan base for the German car maker. This year it took place on 18th May 2013.

Pasadena was assaulted by BMW owners and not only coming from all over the nation, driving even thousands of miles just to take part in the festivities.

And considering the size of the event, it would be plain folly for any aftermarket specialist not to be present and display its best. Many of them brought projects or asked owners to allow them to showcase certain outstanding vehicles.

European Auto Source even shot a short clip displaying some of the Bimmers that turned out for the fest. For a true BMW fan, this is the place to be.
