By 2003 over one thousand cars were attending the event which was by now spilling over onto the roadside and verges for a half mile radius.
Now organised by the
Harpenden Village Rotary Club
, the rally involves more than 1200 classic car enthusiasts driving to Harpenden from all over the UK and beyond to display their lovingly-maintained cars, vans, buses and motorbikes, with an estimated 10,000 visitors going along to take a look at the vehicles on show.
David Law, from Harpenden Village Rotary Club, told BBC Three Counties about the steps taken to reduce traffic congestion in the town during the rally:
"We opened the event an hour earlier than usual in an attempt to spread the load a bit and that does seem to have worked.
"It was extremely busy, but we had great help from the police and our own stewards on duty to make sure the congestion was kept to a minimum," said David.
'Classics on the Common' is a non-profit event, which gives the organisers an opportunity to raise funds for local charities. This year the main charities being supported were Herts Air Ambulance, Herts Actions on Disability and the Rotary sponsored Shelter Box
