I just want to clarify a few things, and maybe offer some perspective on the 350z as an original 240z owner. First of all the 350z is only offered as a 2 seater, not a 2+2, just as the 240z was. Second, compared to the 300zx the 350z has more power per pound. The 300zx was only 300hp in twin turbo form. I believe that this new car has a true 240z soul, which has been gone since the days of the zx's.
The original 240z was such a best seller because it sold for less than $4000. British roadsters like the MG's sold that cheap, but they were not very reliable with a positive ground. The z had two seats, just as the new 350z and unlike the 300zx's.
