I've just done a deal on a pre-reg MINI Cooper and I'm happy with the price, but I've been offered half price (£250) for Williams Racing ceramic coat. Not sure about it, but the consensus seems to be that a bit of elbow grease and a good wax is just as good. I'm buying the car from a franchised dealer who have an admin charge of £30. I've never come across this before from a reputable franchise and, to my mind, it should be a part of their cost of business. Is this a new trend? There is absolutely no mention of this on their website. Unlike the old days, where you could try for a full tank, they now want a flat £30 for half a tank. How do I not know that it wasn't already half full or more? These seem to me to be practices to make up for marginal profits on the actual car.
