The Nurberg ring is not classed as a road i believe, as I know for a fact you dont have to have insurance for it. You would need special track day insurance for it if you want to insure it, but its not compulsory just advised. Tax wouldnt be a problem either, and its not like they are gunna check even if it was. All I was saying, it could just be easier to make the thing road legal and drive there. I dont believe you wil be saving a vast amount of money if any and it seems like a lot of extra hasle. Plus if you ever did want to take it out for a half an hour sunday blast you couldnt. Your just limiting yourself. Plus track days arent exactly cheap. Usually about £100 and then your gunna go through at least a tank of fuel. So if you have the money to do that. Surely you can stump up a limited miliage policy of say 2000 miles for like £500 or something dependant on your age. Plus youll have insurance on it case it gets stolen. You say you want to spend 10k on the car, so money doesnt seem too much of an issue. I think youll just be making things more difficult for yourself. The only real problem I can see is if you make the car un- road worthy with the tuning you do to it. But I doubt this will be the case.
