Why do people buy such cars when they never go off the road ? Daft purchase .
This isn't a personal go at you, but to make the analogy relevant, is it any more daft than having a 4.8l engine in a country where you can't legally drive in excess of 70mph on the public road?
The right to own a car whose capability exceeds its intended or probable use is called freedom (or vanity, depending on your viewpoint). Long may it continue.
