I fancied oneo of these but decided a big coupe suited my needs more. I also think it's a good looking car and better than the convertible, but that's as always a personal thing.
I read the comparison report, which isn't really fair as to me the Zed is in a different price bracket etc. Understandable the BMW and Porker beat the Zed on perfromance which is the most important category for this type of car. Who cares about tax and fuel economy. Not sure I agree with the residuals. In the short term the Zed is holding value well, but as soon as Nissan decide to face lift in a major way, the Zed will depreciate badly. Forunately the MY06 was only a mild change.
As for the dealers, whatever you have to pay for a Nissan service is just a waste of money IMHO, as most are useless..
