IMO, when it comes to seats, 20-way multi-contour seats is the only way to go . . . I now have over 44,000 miles on this car . . . absolutely the best seats I have ever had.
Premium package has many of the options I have always had in my previous cars - garage door opener, rear camera (I also have the side cameras), keyless entry, etc.
Always a succor for technology, after having these I will most definitely order them again - all under the Technology Package - Heads Up Display, Automatic High Beams. Yes opinions vary about these options - for me they are every bit worth the cost.
