The problem with the Polos is that while the new model looks great now, you know that 4 years after it's been released, every second car on the road will be a Polo and then it ends up look very ordinary.
VWs do have great resale value though, and I'm looking to get rid of my Polo and get something that isn't as common, but also holds a good resale value. This is a lot trickier than I first thought it would be.
