I have the opportunity to trade in my 8 month old 90D AP1 for a new 100D AP2 for $17k. On the one hand it's a great opportunity to trade up without the typical huge depreciation, but on the other hand the 90D AP1 is a phenomenal car already and $17k is a chunk of change. Differences I can think of: Although AP2 is a bit janky right now for my liking, it has huge potential. AP1 is as good as its going to get. 100D has nicer seats (subjective, but the newer seats are slightly less bucketed and a touch softer - I prefer them). 90D has matt obeche trim which isn't available anymore - I much prefer it. Currently have pano roof - could pay $2k less and go for glass roof - also very nice - I'm 50:50, opinions welcome. Currently have extended warranty, would not transfer to new car. 90D has free SC, resell of 100D will not (may be moot since *I* get free SC with the 100D if I replace with another Tesla down the road) I'm curious what the consensus is - worth it or not? Also, how much would you pay for this marginal upgrade?
