If you walk around the streets of your average European town, certainly in the UK, the streets are predominantly this type of vehicle. In my town, I'd guess that 60% of all vehicles are small to medium family hatchbacks. Hell, I think I see more F20 1-ers than I do F30 3-ers these days!
At the moment the families with a few extra £ to spend on a car like this don't have that many choices. The A3 and CT are more akin to the 1-er, the closest thing to this is the A/B from Mercedes, which are quite ugly and FWD.... don't hate the player, hate the game!
