i was in talks about buying one of these myself a few weeks ago, heavily modded. in the end i stayed with the Z4, these are completely different types of car, the Z4 demands respect and driving it gives you a feeling of being superior. meanwhile the 350Z, has an absolutely amazing soundtrack however is 255kg heavier, suppose its a personal thing, i didn't want to feel like i was taking a step back by moving into the heavily modded jap import scene again which is mostly full of younger generation.
if i couldn't have the Z4 then i would have no other car than the 350z.
