I don’t like to buy socks without first trying them on. I know that’s a bit extreme, but usually I can’t take new socks for a “test wear” anyway, because they are wrapped in plastic, which I find terribly inconvenient.
When it comes to buying a car, something that cannot be returned and must be lived with for a number of years, I can’t imagine not test-driving it first. Twice.
Yet in certain situations, people are buying vehicles, especially used ones, online without as much as opening the doors to peer inside. That’s just a bad idea, on so many levels!
