The car is awesome. I'm still below 80 miles, so I don't feel I can give it a full review yet, but it is a smooth, quite ride. It almost feels more like a boat than a car the way it feels like you are "floating" over the road. I got the L and it is BIG. I didnt realize how big it looked when I was picking it up at the dealer, but once I approached it from the side when I was leaving work, I could tell how long it really is. However, it doesn't feel big when driving it. The only time I have been concerned with the size is when I go to park and I've found I'm being more conservative/cautious about the size than needed.
The interior is amazing. I was concerned about some comments in reviews about the materials used in trims below Black Label being somewhat "cheaper" and the only pictures or in-person vehicles had been Black Labels until I got mine. I can say that the Reserve is still really nice. I love the 30way seats, it feels like the car is hugging you the whole time and the "massage" is a nice bonus. The ventilated seats are really well done. I've been in cars that have them but you can hear them more than feel them. These you can feel for sure.
I haven't played much with the rear entertainment system yet. I did a quick test of using Miracast to cast a movie from my phone to the screens and that worked. I need to figure how the car handles the audio for that though. I got the upgraded Revel Ultima system and it is awesome. It may be a bit louder on the highs, so I am still tweaking it to find a balance to my tastes.
I couldn't be happier. It was well worth the wait. We have our first kid due in less than 2 weeks, and the car seems to have every feature you can imagine for kids. We got the 2nd row bench, and all 3 seats in the row have the Latch system. The middle row can also be moved closer to the front seats independently of the 2 outer seats. I didn't know it had that feature until I read the official brochure that came out like 3 weeks ago. Also, having both the 2nd and 3rd seats fold flat using the controls in the trunk is awesome. I'm sure it is exaggerated because I have the L, but when both rows are folded down, the cargo space looks huge. I have 2 big dogs so this (plus the first of a few kids) is why I wanted the L to begin with.
If anyone has questions or wants some additional pictures, feel free to ask. I'll try to check here more often so I can answer anything posted.
