You bugger, i have not booked a test drive yet but i am going to as Sarah likes it over the Mini and wants to buy one. I said no as i think they are horrible.
However looks aside, its new, its going to have problems, it will depreciate as soon as it comes off the court and i believe the Mini to hold its value as this will just be a phase and soon, like you say, everyone will have one.
Looking into it, the sport seems pretty good from a spec point of view, however i will let you know the outcome Tim, when i book a test drive.
