You're fortunate to have such a choice. Many company car choosers have a much more limited selection these days. If you don't need anything larger than the A3 you currently have, there's no point in looking at the people carriers. They'll be too big for your needs. If you do want something a bit larger, the C5 or Mondeo are a good bet and the C5 is a world away from the previous model. Both of the options above have low CO2 for cheaper BIK tax too. Disregard the 407. It's at the end of it's life now and not a patch on the C5 or Mondeo. The Focus (which is replaced at the end of the year, but still a great car) and Golf will both make fine replacements for your A3.
