g35/37 for sure. Best mpg of the bunch, sporty and meets all your practicality/luxury needs. Will also be cheaper on maintenance than the S4. And you don't need the awd of the subie (i'm assuming here).
(also, if you feel like modding it a bit, Z1 and Forged are close by are ready to help you out.

)
Oh, and it keeps you in the ol Nissan family. (hugs)
