Well I have to say I think it is Just about worth it.
Only told to be in 3rd/4th the whole time.
But got the Lamborghini to only 5.5 k so didn't get the full power potential of it. Got the back end out a little once which was a laugh, and took over the single seater group.
I will now in the future want to take my car round a track but would need to learn about avoiding other track users as the instrustor in the car said they were his mirrors only.
Bought the missus a passenger ride in an Elise. She loved it.
Was gutted though as the instructor Said 'Are you enjoying it, then once I replied said well your going in now lol.
Heres a pic.
