Nothing.
This has proved to be by far the most reliable car I have ever owned. 9000 miles without a single fault of any description. This is a novelty after the appalling reliabililty of the Alfa 156 which preceded it.
It is not the quickest 1.8 engine around, but is far from sluggish. It cruises at motorway speed very comfortably. The engine is smooth and very quiet. Engine noise only becomes noticeable when accelerating rapidly in low gear.
The car is packed with electronic gadgets including rain sensitive wipers, a reversing camera, a trip computer, automatic climate control and a CD Player.
The seats are a little firm, but can be adjusted to suit almost anyone.
The car is very modern and stylish looking. These are not words normally associated with Nissans!
I agree, I also own a Nissan Prim era SE 1.8 and I'm equally impressed, lots of toys for very little money, would buy again.
