Just found this in the Ts&Cs of the RAC European breakdown cover.
Vehicles which have broken down as a result of taking part in any motorsport event or activity which takes place off the public highway (including, without limitation, rallies or stock car racing) and is not subject to the normal rules of the public highway including participation in the Nürburgring.
Best be careful then. Does Garys track day cover fill the gap?
Most of the other breakdown companies won't cover the car as it's 15 years old this month
