Given you’re reading one of the more obscure pages in a specialist motoring magazine, I think it’s fair to assume that you have a certain idea of what you’re looking for when it comes to buying a car.

That you’ll understand, more than most, the pitfalls and benefits of choosing one model over another.

But imagine you don’t. Imagine, for a moment, that you need to buy something you’ll use fairly often, perhaps for an hour or more a day, but about which you’re not armed with any expertise whatsoever. You could, quite by chance and with absolutely no intent, buy the wrong thing.

It’s a situation I’ve found myself in twice in the past couple of weeks. Once, because my dentist has recommended I buy a water flosser (don’t ask); the other, because I’m looking to buy a steering wheel and a set of pedals to use with PlayStation driving games.
