I wanted about that, so I bought a G37. I might have went with the 5-series instead, but the long-term cost (I tend to keep my vehicles for 6-8 years) comparison of the two didn't justify (for my needs/wants) going with the 5-series over the Infiniti. There are advantages in the 5-series over the G37, but they weren't worth the extra cost to me. I'm sure they are to others though. That's what I decided on though and I've been happy with that decision.
