srt has 330 hp, limited and base models have 215...don't bother with the base models, ugly cloth interior, the sound system sucks, and theirs no of the little luxury items. the 6 speeds are way more fun...out of the cars listed i would go with the 350 or the crossfire, i choose the crossfire, because i see way too many z's and i like the styling on the xf a bit more.

just my .02 cents.
