Agree with the above. I paid £235 for a half day in a Ferrari 360, Audi R8, Subaru, GT3 and Aston Martin.
The Ferrari kept on crunching in third gear and was squealing so loudly on braking it was overwhelming.
Quite often you were not allowed to go more than 50% up the rev range before you were told to change gear.
You were not allowed to go beyond 2k revs in first gear when starting out.
The brake zone markers were miles out - so became useless.
Only 2 short straights - in 3 of the cars I had to do the whole circuit in 3rd gear only !
Out the 5 instructors 3 were particularly arrogrant and rude.
They spent there time not offering constructive criticism but just really heavily criticising driving technique without offering any particular advice on what to do to correct!
They were pushing some people way beyond their limits on a rain soaked track and eventually another older participant spun the GT3 way off the road.
They were doing this in the context that you were liable for the first £2000 of damage unless you paid £20 insurance upfront !
Avoid - better companies elsewhere.
