1985 is to be heralded as the centenary of the birth of the car. Karl Benz is usually held to be the father of the motor car. The French, on the other hand, have discovered a gentleman by the name of de Boutteville who had a car running on French roads a year earlier in 1884. Earlier this year in Paris, the French mounted an elegant exhibition to celebrate this event. William Woollard and Sue Baker visited this dazzling display of invention, exquisite taste and downright quirkiness. Four-wheel drive vehicles made an appearance in 1916 and since then they have acquired a macho upmarket image that has caused quite an explosion in the 4x4 market. Now almost every car firm has a rugged, mud-plugging, go-anywhere vehicle. Chris Goffey assesses some of the market leaders.
