Mmmmm... I always felt like my old RX-8 was nearly perfect. If it had more power, I'd still have it today. But that engine was weak, and I never saw a forced-induction story on the RX-8 that didn't end poorly. A 450hp RX-8 (complete with the back seat) would 100% be owned by me in a heartbeat. Concept looks like it will not have back seat though
