My wife and I are planning to exchange her Peugeot 207 for something bigger and more comfortable for long journeys. We have more or less decided on either an Audi A3 or the Volvo S40. I have done a bit of research on What Car's website. However, on a recent journey from Guildford to Glasgow I hardly saw any Volvo S40s on the road, whereas I saw plenty of Audi A3s. I am beginning to wonder if there is something inherently wrong with the S40 that it does not sell as well as the Audi.
