Overview: Top Gear turns its attention to West Germany tonight with a special programme direct from Europe's major motor show of the autumn which opened its doors just a few hours ago in Frankfurt. William Woollard and Frank Page report from the giant exhibition halls on the latest trends and technical developments. Sue Baker gets to grips with VW's new 16-valve version of its cult car, the GTI, and looks at an accident alert system still under test in Germany. Away from the show, Frank Page tries out Subaru's hi-tech XT model, and there's news from Berlin of a spectacular driving simulator.
