My 2p-worth
Pano - useful for tall people (perhaps in rear seats only?), and for roofbox if you need it (and some after market things like coat-hooks as no grab handles).
Might leak?, over time, colder in winter (Bjorg insulated his because he found the cold from it uncomfortable, I know hiw Norway is colder than our UK, but I'm sensitive to how many kWh might be needed for Heat rather than Drive; also our architect advised us not to have glass roof in fancy new kitchen because cold air, next to glass, would "fall" in winter creating draught. No idea if that scales/applies to Pano though)
Air Suspension - if very steep driveway, off the road, which might catch the nose/tail. If lots of sleeping policemen on certain roads you travel on frequently (GPS will remember where you raised the suspension). Possible better efficiency at motorway speeds. If you have a rough track to your weekend pad then almost certainly required.
None of these things are enough for me, and I think "one more thing to go wrong"
Battery size. If you do longer trips, particularly if regularly, then I would go for largest battery. You are in UK not USA? so I figure that a long trip isn't a motorway cruise from London to Edinburgh with a Supercharger every 2 hours but rather A-to-B-to-C-to-D. Might be a supercharger along the route, but if you are not a BEV driver already you are probably used to pressing-on at 80-whatever, rather than drop speed to 50 or wanting/expecting to make supercharger/Ecotricity stops. If you have small kids, or a weak bladder!!, then stops every couple of hours, and charge at the same time, will be fine. Supercharger network in UK not ideal, yet, but enough Ecotricity etc. to get the job done, albeit a bit slower. Battery will deteriorate, somewhat, over time. Bigger battery will have more reserve with time, and also when weather is foul/cold/windy/wet/etc. or you want to do 80 rather than 60.
The 85 battery will charge faster (more miles-add per unit time) at a supercharger than a 70 (I think it is strictly in the ratio 70:85, if so then 21% faster in an 85)
AWD - We fit winter tyres to all our cars. Snow here (East Anglia) for a few days each year, at most, and significant / prolonged snow only once a decade or less. We find that Winter Tyres make an enormous difference. But I live in the country and last 5 miles to home is never gritted in Winter, for someone in town may not be necessary; even in wet, when temperature below 10C, they are better, and if you want to drive to ski resort once a year then winter tyres are magic for that and avoid need for chains on ploughed, but snow-packed, French mountain roads (for example). We used to have 4WD sports (didn't know about winter tyres then), then changed to smaller eco cars and missed 4WD in Winter, then learnt about winter tyres, now we are happy not to have 4WD. However, AWD + Winter Tyres would be my ideal, but I've done French mountain snow-packed road in FWD + Snow tires and easily overtaken everyone with chains and with completely safe stopping distance.
Some people mention that Frunk is smaller - I think the cargo space, overall, is MASSIVE, so unless you have something you specifically want to store, and leave, in the Frunk (I've heard Child Buggie/Stroller mentioned) then I am doubtful that the AWD loss of Frunk space is significant.
AWD as I understand it has two, different, sized motors. So at motorway cruising just the motor with best efficiency for motorway speed can be used, whereas single motor is a one-size compromise. I suspect this is what leads to better range - so if your "range" is all motorway you may be better than advertised (whcih I presume is based on a "mix", if only in town then no difference or a negative?
Auto-pilot. If you are buying new then retrofitted is GBP 500 (I think) more than included in initial purchase. If you are buying used then its probably "free" compared to a car without it. Either way, for that reason, it will help 2nd hand value (but not recoup any additional initial expenditure).
All that said, I'm not an owner, so this is just from what I have read. I'd welcome anyone correcting anything I have got wrong, and other opinions on the "subjective bits"
