Drove the rwd 70 yesterday and a 90D. Mother of God, the 90D was crazy. 70 is quite a car itself. Still don't know what I'm going to do, but I enjoyed the test drive
Comes down to your budget really....85D/90D is a big step up financially from a 70 or even 70D if ordering new.
I don't feel any of the options pkgs are must haves anymore except for AP. Textile seats are really good and piano black trim looks great. Standard audio sounds really good. (if you were going to upgrade I would stick to standard and then add NVX sub pkg which sounds better and saves $) Pano roof isn't very expensive anymore if you prefer it.
If going CPO I would want lightly used with AP, but I don't think you will find that, and if you do, chances are it will be fully loaded or close to it, which will kill your budget anyway.
The D will give you better traction, better acceleration, better handling, and a bit more range. But the RWD is no slouch in any of those categories either, and will give you more frunk room, and will be a bit quieter, plus saves you 5k. And if you go 70D, it's only 5k more to move up to a RWD 85, but I think the AWD benefits are a better bang for the buck than the increased range on the 85, unless you are road tripping all the time.
So, I would be ordering a brand new 70 or 70D with AP and pano (if you like), no other options, textile seats (or next gen if you love them).
Ordering new gives you no surprises, and the build quality now is excellent. Plus, you get the option down the road to extend the warranty.
