When I was a teenager, Aston Martin Sales had a showroom opposite my Aunt & Uncle's flat in Sloane Street. I remember a beautiful and very nearly new V8 they had for sale with less than 500 miles on the clock. Talking to the salesman, he told me that a customer had bought it without consulting his wife. After a couple of months of driving the car around London, he decided he just couldn't face owning up to his

that he'd spent all that money on such a thing, so had brought it back to be sold.
