If you guys had to pick which one of the above mentioned cars would you pick?. All being sedans.

All good choices, but IS F would be mine.

Hard choice, i would probably go with the M3 but what years?

hard choice between isf and m3 unless the m3 was a coupe then it would be m3 for sure

M3 for sure

Defiantly M3 with real 6mt WIN!!!

Definitely the M3. No questions, but Id take tye CTS-V over all of them.

as great as the M is, I couldnt see myself making that purchase when a 335 is SO much cheaper and it's so easy to tap the potential power out of those bad boys.

tough decision though. i still couldnt decide.

2012 RS4 an option?

I am with the cts-v if it had to be one of the cars on the list I would go with the m3

M3 > isf

M3....even though I prefer the coupe over the sedan.

335 are way to unreliable all my friends with 335 spend more times in dealers due to issues than my G for oil changes.
Plus M3 looks so much nicer than 335.
