Sorry, I don't have an E90/92, but if anyone is interested...
The next National Capitol Chapter BMWCCA social will be this Thursday, June 21 at the Zodiac Lounge (Gaithersburg)!!! It's a great chance to meet fellow BMWCCA members, eat free food, and have some drinks.
All the information you need is here:
