This Porsche 924S cost £300 to buy. It was completely road legal and came with a valid MOT certificate. It was driven to the circuit. It was driven home afterwards. A full day on the Oulton Park rally circuit costs in the region of £100 for unlimited access (ie an unlimited number of laps). Even if you crash your car and it's unrepairable, £400 for a full track day is cheap (a track day in a Boxster or 996/997 will cost you that just in tyres!) Is this the cheapest and most fun Porsche motor sport there is? We think it probably is!!!
