I agree with Paul.

Wayne has failed to take in to account all the 'incidental costs'. Those Zinger Tower Burger Large Meals and Pints of Stella dont buy themselves!
I only work half days but I must go through £20 a day in Brake and Clutch cleaner and latex gloves, and that is before I get anywhere near the car. The cost of cardboard is also going through the roof and you even have to put the holes for bolts in it yourself!
