Save some cash and get a WRX instead!
You know I had to say it, but honestly I'd recommend Subaru all day long as I've been super happy with them.
Plus Infinity is just a more expensive Nissan.....but you know this. I actually remember you talking about how good Infinities were years ago....I did check, but they are pricey for what I wanted.
P.S. If you do consider it I'd let you take my car for a drive to see what you think (well with me as passenger); I don't do this for anyone, but I know your stick shift skills are on point
