What are your expectations around making the original post? Ranting? Informing people of tesla's poor panel gap quality? Making conversation?
On a side note, there are many times when a business does not want a customers business. for just about any car dealer, if one pulled out a caliper and didnt buy a car, they would likely tell you (either politely or less politely) to go pound sand and take your business somewhere else.
This would be kind of like taking a meat thermometer with you to a restaurant, and checking the doneness of your steak before you cut into it, and sending 4 of them back because you asked for medium rare and the temperature of the meat was wrong. You are certainly within your right to do that, but its also a quick way to look like a $#^^%#$% or in less virtually colorful terms "look very difficult to please".
If it was visible to your naked eye, you should have kept going with that. I dont blame them for saying they would not order another car for you. Its a virtual certainty that you would "continue to be the same type customer" after delivery of the car and they are likely hoping you choose to move onto another brand.
Let me be clear... you are well within your rights to make whatever search criteria you want to in your search for a car. They are also well within their rights to not desire to do business with you because they do not feel your expectations and their product will align.
My BMWs have had much better panel gaps than my tesla does. My wifes X3 is an extremely well made vehicle, its fast, its comfortable, since its an M40i, it has a nice exhaust note when you start it up, has 350+HP, and even pops and crackles when you get on the accelerator. Its a very nice car... that I cant stand to drive since I got my model 3.
I am willing to deal with some of the issues tesla has to have the driving experience. it appears you are not. Thats fine of course, but I dont think you should buy a tesla, at least not yet. I would suggest waiting until one of the german brands comes out with an EV and taking a look then. They will have better panel gaps, and a large dealer network (and likely worse range, and slower, and not handle nearly as well, and a less expansive charging network).
I am willing to deal with some issues. As I said, about 50% of the cars in the lot were OK enough that it was not enough of an immediate eyesore. maybe 1.5x gap size on one side not 3x.
I was just curious how many people find something like that and eyesore they cant ignore. I figured it would be less than 25%, else Tesla would be in trouble. It is still a pretty large percentage so far though...
