I have a Groupon voucher for a Trackday to drive 2 cars for 3 laps each around the track in York. The cars are a Subaru Impreza and Mitsubishi Evo which you get 3 laps each in. The voucher is valid from 8th Oct 2012 to 08 Jan 2013. The voucher cost £69 was purchased for my birthday but doubt will ever use it.
