Dude. just get the damn Z its better. And Women Love it just ask my aunt
that went from 2011 SLK to 2011 Z love at first site, but a brand spanking new Z its really harsh, noisy, nasty, clunky, after about 6k miles it becomes much smoother better and if you put diff tiers on it it becomes much quieter. I must admit the seats are sooooo comfortable
