Any specific reason you do not want an Infiniti?
I think for the money spent vs. what you get it is by far the best brand out there. Not to mention resale on them is actually pretty good. Maintenance costs/schedules are minimal and can be taken care of at a Nissan dealer for a noticeable amount cheaper. They are extremely reliable for being a "luxury" car, that being said I would personally buy a Q50/G37x CPO before anything else. I feel like an Infiniti is much easier to deal with, all the electronics systems are very well thought out and user friendly. It isn't like an Audi where it will take you 15 minutes to get into the screen to add a radio preset, and another 10 minutes to add a preset. I'd at least go drive the shit out of a G37x, or even a G37xS if you can find one locally.
Pro- No CVT.
Con- Flappy paddles
Just my $0.02 though.
Re-read initial post, here is a good example. It is even white and they have plenty of head/hair room.
