Video group test: Audi v Merc v VW
To see how the three compare, we put them up against each other in a video group test.
In our test the Audi A3 1.4 122 SE goes up against the Mercedes A180 Blue Efficiency and the Volkswagen Golf 1.4 122 SE 5dr.
All three cost from just under £20,000, offer a small economical turbocharged petrol engine and all the equipment you'd expect from a premium manufacturer.
Watch our video road test to see how they performed.
