The Historic Endurance Rally Organisation (HERO) is holding a draw at Race Retro (22-24 February) with a £6500 prize of an entry for the 2014 Winter Challenge, plus a rally-prepped Ford Cortina GT to do the event in.
The competition is intended to promote HERO's Arrive and Drive scheme in which enthuiasts can 'hire' suitable classics to use on the company's events.
To give potential customers a taster, HERO is repeating last year's successful Race Retro Arrive and Drive formula.
For £25 visitors can take out a professionally prepared car on a specially designed rally course.
The cars include Alfa Romeo GTV, a BMW 1602 and a Ford Cortina GT and, following high demand last year, people are advised to book in advance.
If you can't get to Race Retro, you can also enter the draw on HERO's website.
