There are a number of checklists, the one I liked, but can't remember where I read it (not helpful, sorry, but I remember the principle), is the priority is to check areas where you could possibly cause damage yourself after you drive off. So panel gaps, seat adjustments, failed interior lights, washer jets not firing, headlight alignment and water in lights etc are all things that would be warranty items later, ne real debate and you'd probably take the car regardless, whereas a scuffed alloy, stone chips, scratches in the paint and damage to the seats, they're all things you could possibly cause yourself and so could lead to a debate. They're the things to focus on while there.
Oh, that and numbers plates front and back match!
Seems pretty logical and quicker. I guess their 100 mile range thing is their attempt to avoid it too.
