I LOVED Mine. Follow the link HERE, you'll see I wrote fairly in depth about it before its untimely death.
There's not a great deal of K13 owners around these forums, so feel free to take this to PM after you've read my thread.
I cannot stress enough how much fun it was to drive, mine was a facelift DIG-S Tekna. That's the top trim level, and honestly, it's worth paying a bit more for the top of the range model.
The supercharger provided an excellent boost in acceleration, which made it great fun to drive, whilst retaining 60mpg. If I could afford another, I'd be at a Nissan dealership tomorrow.
