Def. concede on the Ferrari V8s, but only because they're low displacement, high-revving, high-strung V8s. I love dat exhaust note.
I'm not a big fan of the deep, burbly exhaust notes of the big displacement AMGs, muscle cars, etc. Not that I don't like them.. they just don't really excite me.
Edit: actually, you know what, I'm gonna admit I don't like AMG exhausts at all. They're so dull to me.. sorry JayJay..
