The best "driver's circuit" in Europe is woithout doubt Spa in Belgium.
Never been to the circuit myself yet. The first free week I get in april/may me and the 3.2 are booking a track day at Spa. Several UK companies organise tours with hotels and usuall one evening session followed by a full day on the track.
FWIW - why not use the miles to visit Le Mans? There is obviously much more racing going on, and there is access around almost all of the circuit. Best of all the whole event is much more sociable, once you've been you'll want to return every year. Plus you might get to see more of your favourite cars. Don't forget you can access the pits and talk to the teams more easily. You can even drive the circuit ? don't forget the fastest car is a rental car,
This year it will be arounf 15th/16th June.
Any truth in the rumour there might be a Porsce Carrera GT competing this year?
