By the end of 1930, the Club had 852 members, and was already claiming to be the second largest such club in the UK. Its importance in the world of UK motor clubs was recognised by the RAC, which invited the MCAC to nominate a representative to be a permanent member on its Associates Committee, one of only five such clubs to receive this honour. By the 1930s, the Club’s political influence was declining, notwithstanding the presence as Vice-presidents of no less than 16 MPs representing all the constituencies in the County. However, its 18-member committee was organising as many as 15 events in most years. The most notable of these events was the 100 Miles Reliability Trial, that was held every year without a break (except during the war) from 1907 to 1939, taking competitors in this ‘closed-to-club’ event to all points of the compass within approximately 100 miles from home.
