For A small car with Audi qualities and the Audi badge can't fail. All the petrol engines are good, and quality is up to the usual Audi standards. The A1 has a far bigger boot than the rival Mini.
Against As you progress up the trim hierarchy, you get firmer suspension, bigger wheels and a firmer ride. Diesel engines are noisy.
Verdict The Audi A1 makes a fine used buy. It has all that's good about the brand in a package less than four metres long. However, unless you can live with a hard ride, avoid the firmest suspension and biggest wheels.
Go for… 1.4 TSI Sport
