I'm probably in the same situation many are in. I have a perfectly good car that I bought new: 2017 Mazda CX-5 GT/ AWD, with every option, perfectly maintained with 48k miles. With the current vehicle shortage my Mazda is probably worth $3-5k more than it would be under normal circumstances.
I've driven the MY Long Range a few times and I'm impressed overall but feel some of it is just odd. I'm going to list some of my concerns about the car and hope some of you here in "the community" can help to quell them.
Frame less doors- The windows roll up/down every time the doors are opened and closed to clear window trim and seal windows better when doors are closed. This seems to be something that was done intentionally to secure repairs later in the vehicle's life cycle.
Sunroof with no shade- It gets damn hot here in Oklahoma. When I test drove the MY I noticed that whatever space age glass Tesla put on this roof it simply doesn't block enough light or heat. I understand there are aftermarket shades but from what I've seen most sag in the middle and look tacky. I've talked to a couple of tint shops and one refused to tint it stating that it could cause heat to build up and crack the glass and the other said they wouldn't because they didn't have the template. This is one area that I feel Tesla really went cheap.
Spartan Interior- This is a Love/Hate thing for me. At first the novelty of it took my breath away. Then I realized almost EVERYTHING is controlled through the display screen. I think there should be either a heads-up display or a small instrument cluster. Although, I did find that I got used to using the center display for speed and other functions. My biggest pet peeve is no dedicated door lock/unlock button.
Thermal battery capacity loss- I've watched several videos discussing this topic and it looks like extreme cold can impact range by over 30%.
Electric door release- The only way to open the doors (from the outside) is thought the electric release door handles. How do you get into this car if it goes completely dead?
I'm still muddling through details and haven't placed my order yet. Tesla's site currently states the delivery date as 6 months out but a service center associate told me delivery would likely be 2-4 months.
I think if you've test driven the MY several times and still have a lot of reservations, I would tend to think you shouldn't buy the car.
For me, I researched the MYP a lot and did a test drive where they let me keep the car overnight. I was almost sold going in and the test drive solidified it for me and I ordered on that night.
My take on some of your concerns:
-Frameless doors: As others have mentioned, the up/down sealing action is normal for this type of design. What does concern me is that the up/down sealing function is tied to the puddle lights. If the puddle light goes out, that window will not lower and you would damage something when closing the door. I have a friend who had a puddle light go out and when his wife closed the door it damaged the trim because the window was all the way up. I installed aftermarket puddle lights so I will try to be extra careful about it, but not great to know that it might cause a problem and I would not be covered by warranty.
-Sunroof: I'm in Minnesota and had the car since 9/1. I don't think there has been many super hot days since then, so it's hard for me to say how much of a heat issue the roof causes. But I'd estimate we get maybe 2 weeks of 90~100F weather in the summer, so it shouldn't be an issue here.
-Spartan interior: My first impression was really negative. The first time I checked out my friend's MY and thought it was extremely down market. However, on the test drive I completely changed my mind and thought it looked pretty decent. Not luxurious by any means, but "down market" was no longer anywhere on my mind. I also thought I might be bothered by the lack of an instrument cluster in front of the steering wheel, but even during the test drive I did not miss it, and having driven the MYP for a month now, I have not missed it whatsoever. I do love the giant screen and have not had any issue getting used to using it for all the functions.
-Thermal battery capacity loss: I knew that's going to happen in the winter in MN, but figured it wouldn't be a big enough detriment for me to getting the car. I guess I will find out soon enough.
-Electric door release: I don't know what would happen if the car dies. Hopefully it never comes to that.
I feel like there are going to be a lot of competitive options coming to market in 2022, so if the MY doesn't do it for you, there will be plenty of other good option in the same price range available soon. That said, I've been extremely happy in the month I've owned the MYP. I love how it drives, I actually enjoy the interior, and the bells and whistles works EXTREMELY well for my current lifestyle (such as Dog Mode for our new dog, video streaming on large screen while waiting for kids during their activities 3-4 days a week, no range issues for my driving needs, etc.).
