Hmmm thats really not a bad price for Haynes but i'm just worried about a few things, not sure how big the track is but it seems like more of a museum with a small track so not sure how big/high speed it is? Also noticed that only 1 person allowed on the track at once so then the £60 doesn't become so cheap if we're waiting about all day. Obviously i've never been but im just wondering if a proper trackday is more worthwhile.
I recently went with a friend to a Toyota owners club trackday at Bruntingthorpe and although its £50 more at £110 I think it was really worth the money. Open pitlane, as much track time as you want and unlimited number of cars on the track (within reason). The track is 2.1 miles long and ranges from about 30-40mph all the way up to a 105mph corner in my mates Lexus

I'm not sure what other cars would be on the track or how they set it up (the main straights were broken up into bends with cones when I went) but the next one is 3rd June.
On trackdays.co.uk the next Anglesey trackday is 9th June and £140, not sure if they do others?
