Do you actually mean "per driver" there mate?
As that makes it sound like if two people share a car it will be 119 + 119 = 238 quid, where as I suspect it will be more like 119 + 20 = 139 quid.
Would have liked to have done this but I have so much on in june already that im not going to get a chance, will be interested if its a success and hence you do another one later in the year though
