The inventory 100D was $99k with premium package and autopilot. The interior/exterior color didn't match what I wanted, and it didn't have the sunroof (which I need because I frequently use roof racks). It was $10k off MSRP because it had 1200 miles on it as a demo car. I didn't care about that. My 75D came out at $92.5k, so we were still talking about $6.5k more. I know that's not a lot of money, but I'm already above budget because I didn't plan on getting premium seats (thought these were part of the premium upgrades package) and sunroof, which combined are $5k. So I was already starting above budget.
I asked him if they would meet me halfway at $95k and if so, I would sign then and there. He disappeared "to call his manager", which is one of the oldest car salesman tricks in the book, something I thought I could avoid buying a Tesla, and came back and said they were firm at $99. I respect that Tesla doesn't haggle, so I wasn't upset to walk out of the store, which I did. However, he definitely had a look of shock on his face when I said no thank you and left.
Either way I win - I still get a Tesla. Some people are saying the 75D makes "no sense at all" when you can get a long range Model 3 for less with more range. Range isn't all I care about. I want a larger, comfortable vehicle with high end appointments and tons of room. I also had a requirement for this purchase of purchasing a hatchback, which immediately eliminates the Model 3 and knocks out pretty much everything else in this price range, except maybe the Mercedes E-class wagon, but a wagon isn't a hatch back - it's still a compromise.
I used a couple of the online EV trip calculators to check every conceivable trip that I may take in the next 5 years (I'm a creature of habit so this was easy to do). There will be only one trip that has me stopping more than once at a super charger - I drive once a year into the hills of the Pocono Mountains in PA to visit family. It's very steep hill climbs and a long distance from my home in Boston. I could stop twice and charge for 20 minutes both times, or stop once for an hour and charge. I have a dog so stopping twice on a drive that long is what I already do. I don't mind just setting the autopilot to speed limit +5 and getting there when I get there.
Since it's a family house, I can bring an "extension chord" and plug into the dryer plug. I'll just order the adapter directly from Tesla after a family members texts me a picture of the outlet.
And I think the most important part - it makes absolutely no sense to spend $6,500 to buy a car in the colors I don't want, just to complete a drive I will only perform 1x a year. I can rent an ICE for the trip going forward if it doesn't go well after the first time.
Another argument I heard was that because I live in New England, where it's frequently below freezing and can be single digits or even negative F for days at a time, the 100D will be useful due to range loss from cold weather. I think this can be pretty well mitigated by preheating the battery, which Tesla now lets you do from the App. My understanding is that if I get the battery up to operating temps while plugged in, my range in cold weather should be similar to normal range. The range loss from cold weather is a result of the battery sitting out and getting cold. Correct me if I'm wrong.
A huge benefit for me, purchasing any EV with this type of range, is the weekly trips I take up to NH to stay at my cabin. It's only 120 or so miles so it can easily be done on a single charge - paying for gas for 40+ trips per year adds up fast, as does maintenance on an ICE vehicle. And there is a free public charger on my street! Literally 100 feet from my house AND I get free charging at work. Combine that with superchargers, and I can go a majority of this car's life without paying for electrons.
