I ordered an 85D, and I considered some of these same issues for my second car
Air suspension - I have it on my first one, but I am thinking of leaving it off. I test drove one last weekend without suspension and didn't miss it. I know I drove over potholes. I kind of feel like its one more thing to break in the future.
Ultra high fidelity sound - didn't get this on my first car, getting it for the second. But its one thing I have considered dropping. It's clearly better but is it that much better?
Pano roof - highly recommend this. As others said, you can avoid alcantra headliner too.
The fancier upholstery with yacht flooring seems the most silly feature.
I didn't get dual chargers the first time, I got them this time. I have regretted it but it is mostly future proofing. So much cheaper to get it from the factory
Tech package -I didn't get it on my first car. I have only missed it a little bit with maps in canada. But now that tmobile supports data in canada I just turn on my phone there as a hot spot and connect my car to it. But on the new cars this is crucial because of the auto driving car features
subzero - that was not available when I got my car, $750 seems like a good investment here.
Leather seats or texture- long ago when dinosaurs roamed the earth, when I ordered in 2012, it used to be that you didn't get heated seats in the front unless you got leather. I'm informed that now all front seats are heated, including texture seats. I was thinking of downgrading my leather seats but I'm not sure. I've never even seen a texture seat. Neither had the sales guy
I'd group the options this way:
Must have:
85 kwh battery and D - if you ever use your car in frozen weather, get the D. The 85 is a no brainer unless you are really sweating the cost. I'd get it anyway
tech package
Almost must have:
pano roof - works great, also get roof attachment and avoid paying for alcantra.
Not as clear:
subzero, ultra high fidelity sound - I didn't get the better sound, I don't miss it that much. I'm getting it this time though
dual chargers - but I'm getting it. This is the single thing I have thought of retrofitting my original car with. However there have only been 2 or 3 times I could have used it.
electric suspension - unless you have a really steep driveway.
Wouldn't even consider getting
Alcantra headliner.
What I really want to get but can't:
upgraded seats. shutup tesla and take my money for the seats, please!
