Before my Z I drove a 2005 Crossfire SRT6, which is basically a rebadged SLK. All the components from hoses, to exhaust, to supercharger are badged Mercedes. That car was awesome! The power from that FI v6 was amazing. That being said, I think the ride, comfort and handling of the Z are much better. I went 207 350Z to the SRT6 and now to a 2011 370Z. Hope that opinion helps, it is after all, just my two cents.
