Hi,
I looked at the RX8 before I got my Zed.... and I am glad I got the Zed. I found the RX8 to be a harsher ride, although look nice I think the Zed looks much better.You will see fewer Zed's on the road.
I average 24-ish mpg (spirited driving to work and back) and I don't have to pour oil in to keep the wankel engine happy.
You wont be disappointed with a Zed !!!
