 Most comfortable and capable sedan I've ever had.  This is the 3.8 AWD model with all options (Ultimate Package).  We got the Genesis in late April 2016 and due to several unusual events have put quite a few more miles on it than I expected (8023 miles) .   Many have been highway miles with Adult rear seat passengers on long trips in hot weather.  That has given me a chance to really get a good feel for it's capability.  I love this car, it's extremely quiet and comfortable for all occupants especially on long trips (over 900 miles in one day).  The options work together extremely well and driver fatigue is a non-factor.  The dual zone AC works very well for the passengers each can control the settings as they wish and the rear air is very effective in hot weather.  The driver aids are spot-on, I love the adaptive cruise control, blind spot detection, the automatic and speed sensitive wipers, and we've use the Blue Link quite a bit.  The ability to control the driver interface features (Nav, audio and media input)  from both the console as well as the touch screen and many features from the steering wheel is very effective, I think it's a Genesis exclusive.  Using regular gas and the multi-access driver interface (as well as the price) made the Genesis stand above the Lexus GS for me which was runner up.  We've averaged about 24.7 mpg overall to date.  I drove just about every vehicle in this class (much to my wife's annoyance) before I selected the Genesis and have absolutely no regrets.  No maintenance history to report so far, just coming up to the first oil change.  If your in the market for a comfortable large sedan you can't make a better choice than the Genesis.
