Episode 4

Are the days of the traditional, much criticised car service numbered? Chris Goffey looks at a new breed of cheap, fast-turnover, top-you-up operators — US-style franchised chains that look set to revolutionise servicing and threaten one of the bastions of Britain's garage trade. William Woollard takes to the kart track — the training ground of future Grand Prix champions. There's a road test on the Renault 21 and Sue Baker finds out what special 'magic' a car needs to make it a classic.
