Alreet!
Just get a 350z and be done with it. The others are just 2 seater sports cars, the Zed is like that old friend that makes you smile every time you get together. If it's not the wicked power then it's the noise it makes, and even if that doesn't satisfy you then the looks of approval/disgust/bewilderment will always put a smile on your face!
I was in the florists the other morning getting Mrs OV53 a bunch when I saw a bloke in his late 60s double back and start looking around the car, his wife patiently waiting for him to complete his inspection, after which he walked away with a puzzled look on his face. Obviously the lack of the 350z badge or a Nissan badge had sent him, but the sheer fact that he obviously liked the look of the car and took the time out of walking up thr street with his missus to walk around and try to figure out what it was just gave me a sense of pride that you wouldn't ordinarily get with any of the other cars you mentioned. It was just a shame that the bouquet took too long for me to get in the car and give it a little burst past him as I'd just fitted the Amuse exhaust about 15 minutes earlier!
So....yeah, get a Zed!
