Infiniti M45
Its a nice car. Just a few items to think about:
1) Owners are avg 12-15 mpg.. on a car that is fast but not AMG/M fast.
2) I dont know what your looking for but its a bigger car and does not handle that well. But you know as you had a Q before. Its on par with the GS.. I also was not that impressed with how much faster the V8 felt than my old GS400.
3) The suround 5.1 bose sound system is AMAZING.. when you use DVD-CD's it kills the ML systems that I have listened to... Find one with that set up I mean it has speakers in the Front seats-- How can you lose?
4) I am not sure, but I dont think there are a ton of aftermarket perf parts available for the M45.
5) They are a killer value right now, so don't let the Infiniti haters on this site deter you.

I know they are very reliable with a few wiggles here and there.. Very similar to your GS and your Q...
Good Luck..
One thing that I don't like about Infiniti, my paint job is not great. I think its much lower quality and probably thinner than the paint on my old Acura CL, and not as good as on my BMW. The Infiniti seems to get paint chips much easier than my other cars, and has more noticeable orange peel. Since Lexus paint quality is better than all those brands, you may want to look out for it.
