Had a couple of RX8's before the 350Z and have no regrets changing to the Z. Really enjoyed the RX8 and was great for chucking around but really love the power (torque) delivery of the 350Z and the V6 sound track.
I considered a 350Z when buying my first RX8 but did not like the interior but would have been comparing a 350Z that was a couple of years old with the more modern look of a brand new RX8 - and thought the RX8 interior and useful back seats was fabulous plus the 'novelty' of a rotary engine.
I kind of forgot about the 350Z (sinner) until I went to look at an HR version with Rays alloys and better quality interior and then had to have one.
Both great cars but I enjoy the 350Z more. Take one for a good test drive and see what you think.
Just had a look at your RX8. Still love the interior and looks of the car. So much car for so little money. Shame their starting reputation and engine longevity killed the market for them. I have had 2, neither ever failed to start, but the RX8 forum made me paranoid I must admit.
Yeah thats the thing that got me with the 8 when I started comparing it to the Z, the interior!! The 8's overall package has a lot more going for it. I can comfortably fit 4 adults in it along with any luggage. It really is the engine that lets it down the most and sadly there aren't as many options available to fix that. Even a rebuild with bridge ports only adds 10-20hp but it still feels just as gutless.
