I'm not sure its twice as good as a 350z to justify the 60k price. Furthermore, by the time its for sale it will probably be in the 70-80 range. Which means same price bracket as the zo6 and viper, both of which are faster. Not to mention in that range there are also several sedans which make more hp.
Not sure what Nissan is going for with this car. 45k, with no dealer markup, this is a runaway hit. But at an inflated price, it may see a similar fate as the NSX.
