Despite strong challenges from Land Rover, Jeep and Toyota, the world's best selling four-wheel drive remains a good old American Ford. The Explorer has also gathered quite a following in its time on sale in Britain, making life tough for the British, American and Japanese establishment. While the Explorer may not be a particularly familiar sight throughout the UK, our American cousins snap up over 400,000 examples every year. This imposing off-roader is the archetypal American import and commands a small but significant following in Britain. It is designed for the demanding US market, so it should be no surprise that the Explorer comes with just about every piece of kit you could imagine in a bid to outdo rivals such as Jeep's Grand Cherokee and Land Rover's Discovery. Despite the fact that relatively few have been sold, prices are attractive on the used market, making the Explorer a good prospect as a secondhand buy.
