Thanks again for the posts.
I assumed that they checked the car over then take it away there and then.
Given that I will definatly follow the advice of video/photo the car prior to collection just to make sure.
It has a very small scuff on the bumper which I am happy falls in to the reasonable wear and tear policy (according to booklet anyway). It also has a mark on the plastic behind the internal door handle which was caused when I threw some stuff in on a tip run.
I’m hoping it’s just the alloy they pick up on.
I shall get the Mrs to get tea/coffee, biscuits..... and wear a low cut top
