Whenever the salesman asks if we want shown around the car I decline, I had already test driven it, it has the same no. of wheels etc as any other car and part of the fun is fiddling with it when you get home. Manual is perused as a last resort.
The handover for my S-Max , we drove in, did a 10 min. turnaround then we went on a 300 mile drive as wife had an urgent appointment in Edinburgh.
Had a bit of fun with my Kia Soul as it was set at miles, but the service interval was still in kilometres, even the manual was no good there, but a video (nod to Brydo there) on You Tube had that info so it was all sorted.
In life, it's not who you know that's important, it's how your wife found out.
