Re the reader thinking about a Mercedes-Benz A200: he should definitely buy one. Two months ago I bought my wife an A200 and would strongly recommend it. Having looked at the Mazda3, I found the A200 only slightly dearer yet far superior. The performance of the A200 is more than you would expect from a 115kW turbo — if you want more, there is the A250 Sport with firmer suspension or the A45 AMG.
Mercedes-Benz is really making an impact with its new models and fresh approach to bottom-end pricing.
