Well, dont get hung up on the no key thing, because practically every new car now, maybe sans the cheaper Hyundais of the world and Hondas are going with they "keyless system" Only difference is you still have to put it into the ignition and turn the keyfob thing. I think its called RFID.

Thats a picture of the key my dad has on his new Grand Cherokee. Theres a little slot that is almost like a conventional ignition, but the RFID signal tells the car that the key he is using is the key for the car. Pretty much what I am saying is the difference between that and the nissan is instead of doing a traditional start up motion, you just tap the brake and push a button. I dont think its something to get hung up on.
As for the steering wheel, I personally feel that is the perfect size. its not too small, yet not too large that it takes 2 hands the turn the wheel far.
And Ditto on the blue....ditto. That blue caused me lots of problems actually, because the dealer I went to had the car the way I wanted it in blue, but I wanted black cuz I feel that blue isnt a dark enough. The blue that the Mercury Milan comes in is beautiful, which is what I was hoping for. I had tons of fun getting the dealership to do the dealer trade....NOT. I would go with white if I were you though.
