The Union Concours is a UK-based concours that brings together members (and select non-members) from six exceptional owners clubs; The Drivers Union, Lamborghini Club UK, Maserati Club UK, 96 Club, De Tomaso Drivers Club and the Honda NSX Owners Club—for a judged celebration of standout automobiles across curated classes.

The event is staged at Worth School in Turners Hill, West Sussex, and blends formal judging with a full-day programme that typically runs from morning arrivals through to afternoon trophy presentations. The next Union Concours is scheduled for Sunday 6th June 2026.
