Oxford Diecast has teamed up with CarFest North - the festival of cars, music and food organised by BBC Radio 2 DJ Chris Evans - to give away free model cars and commercial vehicles.
The model vehicles are from the company's 1:76 or OO Model Railway scale range. Typically they are available in stores for at least £4.45 each.
To take advantage of the free model car offer, visitors will need a voucher, which is inserted into the CarFest North brochure. Visitors can then visit the Oxford Diecast marquee - in the Paddock Field - and exchange it for a bag and mystery model vehicle.
All visitors to the show will also have the chance to buy a Lucky Bag, which contains a minimum of £25 of model vehicles from the firm.
CarFest North takes place from August 2nd to 4th at Oulton Park Circuit, Little Budworth, Tarporley, Cheshire. The event raises funds for BBC Children in Need.
