some thoughts from my recent purchase:
- color: i went with midnight after back and forth between that and black. 1) decided that i don't like washing my car that much. 2) my interior was black headliner and black seats so it great to have some different color somewhere on the car. 3) you sometimes don't see all the detail on a darker car. so for me, the midnight silver was a choice that addressed all 3 of those, but it was nitpicky bec i needed a tie breaker.
- battery: i got a 60. my commute is 90 miles, and I can drive around all weekend before i 'need' to charge. it also depended on my budget. this was the the max that i wanted to spend on a car so anything extra had to add value. the extra battery didn't because i would not be using the additional range. for the past week, i've been charging to 140 miles and it has been more than enough. so if i paid more, it would just be sitting there and i'd probably still charge to 140 miles. we also have a van for longer trips so that wasn't ever going to come into play for me.
- seats: didn't get next gen seats. wondered about that too but the basic ones are nice and comfy enough, and other friends who have seen the car said looks/feels sporty. also, because it was on the upper end of budget, the value i got from the seats wasn't worth it for me... but that's just me, because i found the existing seats comfortable and sufficient. others really need leather, which is a personal choice. i also had a hard time getting in and out of the next gen because of the sides and didn't want to have to get used to that.
if it were me, I'd go for 3K less but mostly because i ended up picking midnight silver and was good with the next gen seats and didn't need the battery. every situation is different so good luck!
PS on the color. I had questioned my decision while the car was on order but I think it's because it's hard to visualize this color in my mind. any time i saw it posted and esp when i saw it in person, i remembered why i chose it in the first place.
