Hi Alan,
Do you mean this outfit..?
https://www.classic-tracks.comIf so, whilst I've no first hand experience of them I DO know someone who has driven on track with them, and was very impressed with his feedback.
It's owned & run by a Morgan man on here, Sprinty.
From what I hear, I'd have no qualms about having a bash with them rather than an unknown outfit, and I'm seven tenths coward in my DNA..
