Aston Martin have introduced a new version of the DB5.  It has all the Goldfinger Bond gadgets, including the bullet proof rear screen that has been tested to withstand .357 Magnum, so it's OK to drive away from various access and committee meetings if they don't like your vote.  And the machine guns are installed if something more diplomatic is needed.  Costs the best part of ?3m quid each, so one per committee member for official BCA business is ideal.
