I'm a recent Nissan convert and diehard fan. Out of the Japanese "Big 3" , Toyota , Nissan , Mitsubishi (Or Subaru) , (Maybe "Big4" if you include Honda , but they havent built a decent sports car since the CRX) I've come to the understanding the Nissans are the most reliable , with Toyota 2nd , and Mitsubishi and Subaru a distant 3rd. I have an '85 Turbo 300Z , and it seems just as solid as the day it was new. No squeaks or rattles , engine runs like a top with 160K on it , shifts are notchy but accurate. Technology has gotten much more precise since then , so I imagine a 350Z will outlast even cockroaches.
