The Festival of the Unexceptional is expected to make its return to the Whittlebury Park Golf Club, Towcester in 2015 following the success of the inaugural event. It has been slated to take place on 25 July.
Last year's show was headlined by Princess Diana's Mini Metro, while a 1985 Nissan Cherry Europe beat a '75 Austin Maxi to the top prize. In total, more than 50 cars took part.
This summer's event is set to be even bigger than the last, with news of the show reaching far and wide; a group of 25 cars is anticipated from Holland.
Managing director of Hagerty, Angus Forsythe, said: "Last year's event really captured the imagination of people up and down the country. This is not about expensive classics, but a celebration of the cars that many enthusiasts used to drive.
"From the Austin Allegro to the Triumph Dolomite, we will be looking to make the mix of entrants at next year's Concours de l'Ordinaire even more eclectic. Given the increasingly rare presence of these cars on Britain's roads, this event will again give loyal owners the chance to show off their mustard brown paintwork and Rostyle wheels in all their finery."
