It's a total lottery. Car is amazing when it works. My 3rd row seat broke today so now it's stuck in a flat position. I'll need to call to set up a service appointment. There's definitely highs and lows with the car.
The experience from the OP sounds terrible though. It was much, much better than that here in Austin. I was never rushed and they never gave me an ultimatum, though I never really talked about the option of rejecting delivery. I tried to be as gracious as possible. Sounds like the people working in that particular SC were a lot worse though.
If the panel gaps are too much out of alignment with each other, I would think long and hard about accepting the car, as they said fixing those means having to go to the body shop since a lot of those panels are welded onto the car. My main concern wasn't about the looks so much as the functionality -- it needs to be water tight. As long as it doesn't leak, I'm probably fine.
A lot of what was posted about chrome trim is true. I rarely see it perfect. The worst thing for me was having the FWD take out paint once or twice, and then my third row seat being broken and stuck in the folded position. In general, the car is amazing. It's a bit of a shame that we have to compromise -- choosing either a well-built car or an EV that's amazing to drive. It's a shame we can't have both right now. Maybe in 5 or 6 years, but it's just not there yet.
The pros outweigh the cons, but there are definitely cons if you lose the lottery.
@OP sorry to hear about your troubles. I hope that everything is resolved to your satisfaction!
