Leather Seats - Although we have leather in both of our current cars, we prefer the comfort of cloth seats especially here in the hot desert Southwest. Even with lighter-colored leather the part of the seat you sit on is black which will get scorching hot when parked in our intense sun. However, if we go with the more comfortable Premium cloth seating we don’t get the fold down armrest/cup holders in the Limited’s rear seat which my wife would like to have as she sometimes has passengers in the rear seat. And leather is certainly easier to keep clean.
I live in the Southeast and, while it gets in the triple digits, I don't imagine the heat compares to yours. Based on that alone I'd say go with cloth. The Mrs. will be driving it all the time, where passengers will only be in it part of the time.
18” wheels - From a practical standpoint I don’t view 18” wheels as an upgrade because they don’t ride as smoothly as 17” wheels, and 18” replacement tires tend to cost more. Also, we like the looks of the Premium’s wheels a little better.
I tested both a Premium and a Limited - back to back at the same dealership - and didn't notice a difference in ride comfort or noise. I bought a limited and I've been well pleased with the ride. I agree that the Premium wheels look better, but the Limited's have grown on me.
8” Head Unit - It’s my understanding that the Limited’s 8” HU is glitchy compared to the 6.5” HU in the premium.
Can't opine. My 8" HU has behaved well so far.
LED Steering Responsive Headlights - The Limited’s LEDs are superior to the Premium’s halogen headlights, but are steering responsive headlights just something else to break? Remember all the problems with pop-up headlights?
I really like the LED headlights over halogens. And I've come to appreciate the steering responsive headlights for night driving out of town, particularly up in the mountains. If you are worried about them wearing out, you can turn the steering responsiveness off, and enable it only when you want it.
Push-to-Start – I hate it but women love it. Since it is going to be my wife’s car score this Limited feature in the plus column.
I love not having to take my keys out of my pocket.
Power Seats – Since the Limited does not include lumbar support, the manual seats in the Premium are acceptable since there will mainly be just one driver.
A consideration may be if you can adjust the seat height in the Premium - I don't know if that's available with manual adjustment
Reverse Automatic Braking - This seems rather redundant with Rear Cross Traffic Alert and a backup camera, plus I’ve heard it can make parallel parking in tight spaces more difficult.
I think this is one of those features that I'll only appreciate when it saves me from a major smash-up. I do like the cross-traffic alert. It even warns me of approaching pedestrians.
Automatic Climate Control – My wife doesn’t use this feature on her current vehicle so it’s not something she would miss if she gets the Premium.
This is a feature that I really like, but if the Mrs. doesn't use it, then it's moot.
I hope that my opinions are useful, and I think you'll both be pleased whichever version you get. Looking forward to having you guys as part of the family!
