I agree with PaulM87, I got a 1.4SE and was very surprised at the speed it can achieve - not the fastest, but compares well to my previous car, a Primera on an SR20DE, 140bhp. The 160SR can only be better, obviously.
It also handles very well indeed. When I first got it it felt ever so tall, and like it might topple over. Once I realised that a) it's not as tall as it looks at first glace and b) Nissan don't often make cars that topple over, I got more confident and find it flies around corners, and is a lot of fun all over town.
As for does it look girly... I don't think so. Apart from the one I've seen in Hemel with eyelashes and flowers on it.
