Daily driving for my FX50. Yes, its expensive to run, and I fill up once a week. But its a blast to drive, even in traffic. I agree with many of the other posters.. why buy such a nice car and not use it? I factored in the cost for fuel and maintanence when I bought the car, so no sticker shock for me. I recently got a G37 for a loaner car, and I cant tell you how much I missed my 50. One of the main reasons I bought an Infiniti was because of the reliability, and to know that it will get me to and from work everyday with minimal fuss. So far, so good..
