We PDI'd the one we have today, doesn't have app connect or voice control so I'd recommend getting them unlocked for £400 if you are on android like me. It does look like a GTI which is unsurprising but pictures don't do justice to the brakes which are huge and the tyres which are very sticky. Inside it is literally like a normal one with the seats ripped out. One thing to note is the noise it makes which is very nice.
If you are expecting it to be as different as an M3 is to a normal BMW you will be disappointed. I haven't driven it but the upgrades look like they will make it very fast and capable indeed.
Oh and Volkswizard GT4 has already got pics of his.
