I have a spare circuit passing pass (weekend) that I don't need. It's for 1 vehicle/2 people. The physical pass itself doesn't say it's for 2 people, but I couldn't say if the circuit has a way of telling how many people it was purchased for.
If anyone's interested in buying it do let me know, otherwise I'd appreciate suggestions of other ways to sell it. At the moment the circuit is still selling them at £65, so I can sell at a discount.
