am i right in thinking that if i purchase my ticket for just myself now that if anyone else wants to on the day pay the extra £20.00 to drive then its ok?

like it doesnt all have to be done beforehand?

basically going with the intent that the car probably isnt going to make it back either:-

1) running

2) in one piece

so im happy for any of my mates to drive it so long as i dont have to put twenty quids for them all on my card now

cheers
