For a while I was one a M3 or IS-F phase. After driving the IS-F I knew this was what I wanted. I test drove a C63 AMG just to ease my mind and I actually liked the C63. It's going to be a tough choice. I'm still undecided. Dealer even offered me a fantastic deal on a CPO C63 but I just couldn't pull the trigger. With the torque the C63 feels the fastest and I think it actually pulls harder than the IS-F past 60mph. Really I can't go wrong with either car just I can't get my mind to decide.

If they ate that close in your mind (running cost and spec differences aside) imagine walking out your house to go for a blitz, which would you rather see sitting waiting for you?

Unless you're racing on a daily basis, slight differences in pull/grip/etc are subjective and not really a sound fundamental reason for ultimately choosing an F/M3/C63/RS4 IMHO...they are all absolutely sick. What's really essential is which one you want to drive consistently over the long-term.

Just my $.02
