In the last programme of the series, Chris Goffey tests Mazda’s new sports saloon, the Xedos 9, and assesses how much of a threat it may be to the BMW 3 series. The Middle East is an expanding market for expensive and specialist cars. Jeremy Clarkson reports from the Dubai motor show, and tests the sort of vehicle designed to replace the camel as a means of transport in the national sport of falconry. And Tiff Needell looks at American-style midget racing.
