Nissan makes great cars. I've had several, mostly of the "Z" variety. From what I've heard/observed, the transmissions are the best of the car, meaning very solid.
Many oddly shaped vehicle models now take a certain eye for their liking, like the Nissan Leaf and the Honda Fit. It's definitely an upgrade from a Suzuki though. I don't find the Juke a particuarly attractive vehicle, but ever since the Pontiac Aztek came out over a decade ago, there have been many more "alternatively styled" vehicles available.
I can't recall the name of the current vehicle that has the wrap around the side back window, but wow...that thing is ugly IMO. As far as Nissan, I'd gladly take a GT-R off anyone's hands if need be.
