i know what you mean vinalspin i had a citroen c4 grand picasso i needed a step ladder to get any where near the roof, i attempted it once after that it was the car wash. now the backs gone and the mini will be replaced in 12 months if not earlier by something easier to get in and out of that too will have to be done by someone else.
i noticed the other day a chap on the estate had one of these mobile valeters doing his car so i may make enquiries once the replacement has been found.
