Golley Slater has created the campaign, which is supported by national and regional press advertising and will run until the end of the month.
After taking the test drive, consumers have to fill in a form which is stamped by the dealer and sent to fulfilment house Wegener, according to Golley Slater.
The promotion covers the manufacturer's entire range including the Colt small car, except for the Lancer Evolution.
A similar promotion last year offered £10 Marks & Spencer vouchers.
