BimmerBoard.com is a popular, free message forum for all models of BMW's. It was started in December, 2003 by David Cecil with the mission of providing a censorship-free, permanent repository for technical information as well as for social networking among people interested in repairing, maintaining and enjoying BMW automobiles. BimmerBoard is operated completely by volunteer moderators (28 at last count) who share a passion for helping others with integrity.
BimmerBoard has 50+ forums for all BMW models from the 1950's to present, and is particularly popular among 7-series and 5-series owners. BimmerBoard has several unique forums with content not found anywhere else on the internet, such as the Navigation A/V Forum, the Bluetooth Forum, and the E38 7-series Forum, the largest and most active community of 7-series owners on the planet.
Membership on BimmerBoard is free and open to the public, regardless or whether you own a BMW or not, and registered members receive 50MB of free image hosting.
