If used car buying was a purely rational process, more of us would own a Vauxhall Zafira Tourer, or at least something like it. It doesn’t have the tough appearance of an SUV or a crossover, and is simply a family MPV, so it’s rather bland to look at. However, it is very good at transporting up to seven people, and partly because it attracts no envious glances, a used Vauxhall Zafira Tourer is cheap to buy.
