2007 Hyundai Azera Limited 4dr Sedan (3.8L 6cyl 5A)
Just completed a 750 mile trip to Midlothian, VA from Columbus, NC. Car performed like a charm. Extremely comfortable. According to on-board trip computer, I averaged 29.7 mpg at highway speeds up to 70mph. Better then I ever imagined. Lay off the "heavy foot" and you will love the car.
I had XM radio installed after the sale at a local stereo dealer. It is terrific on a trip. Seats are wonderful. This is a true road car and a great pleasure to drive.
The only improvement I would suggest are daytime driving lights.
