Congratulations! I bought my 2013 SL in November and am loving it!
The 2g obsolescence did become a pain on January 1 at -36*F when in order to get the car to heat up off of charging current several times in a day I had to go out and fiddle with the climate control timer every single time in that awful weather. As soon as it warms up enough to make the journey to the nearest Nissan dealer I'm getting it upgraded!
But other than that it's been a great car! Pure luxury by my standards. Yes, the SL options like the 4 way cameras and the Bose sound system are IMO a bit overkill. But hey! Who says you can have too much overkill!
