Although this new Z looks very different from the old 370Z but actually it is just a slightly modified 370Z with new engine/transmission, exterior and interior...
I think that's why Nissan still calls the new Z "Z34".
Actually I don't really care about Z34 or Z35. If the new Z is fun, I will still buy it...
370Z is already very good. It just needs some refreshment...
The new 86 should have better handling... But, I think I won't accept any car which is below 300hp (I will become depressed )
Of course, I still can put an Ohlins suspension on Z and get huge fun on it...
You can also put a supercharger on 86 to get more power but I think putting an Ohlins suspension on Z is much easier and also more reliable than putting a supercharger on 86...
