A spectacular array of over 1,000 classic cars, scooters, and motorbikes pack Harpenden Common for the annual Classics on the Common, one of the UK's largest one-day classic car events! Visitors can expect to enjoy a wide variety of cars at the event, with everything from 1913 model T Ford and a 1916 Stanley Steamer, to Rolls Royces and Maseratis making appearances in past years. The event is free to attend, though donations are encouraged.

The classic vehicles arrive in two main tranches from 11.30 a.m. and from 2.00 p.m. Most vehicles are in position from 3.00 p.m. to 6.00 p.m. when the first vehicles may leave.
