Went out in one when they first came out (NA version) as a mate worked @ a Vauxhall dealers.
Underwhelmed by the performance, uncomfortable - may as well have been sat on planks of wood, found it laughably difficult to get in and out of. Only experienced it as a passenger, wasn't tempted to drive it. Handling seemed pretty good though.
I'm sure it's much better as a 'drivers' car....but just didn't do much for me I'm afraid.
