Leathercloth. Naugahyde. Ambla. These are just a few of the words that car-makers have used to name vinyl upholstery. Name and euphemistically disguise a badly hidden truth in fact, because vinyl has almost always been seen as inferior to cloth trim or the leather whose texture it mimicked.

Almost, because there was a brief period when vinyl upholstery was excitingly new and considered superior not only to fabric but leather too. Which is how the very earliest, cheapest Minis came to provide cloth seats, while the pricier versions offered Vynide, and unconvincing conflation of the descriptors for the unmentionable vinyl and hide.

You’ll still find vinyl in a modern car, covering door trims, the bits of the seats that you don’t sit on and often plenty more. But what you never find, or so I thought until this week, is vinyl completely covering the expanse of the seat that you sit on.
