Here is what I'm coming from. Buying a new car from a regular dealership has rarely been a fun experience: the haggling, the games played, the obligatory "finance guy" speech at the end trying to sell me some BS warranty, the salesperson who knows less than I do. Tesla has solved that issue. The current long wait times are not fun, but at least we pretty much all pay the same price, and there's no BS game played when purchasing. As for the loaner cars provided by certain dealership today, it's definitely true, but there's no way it'll continue in 20 years when the market shifts to EVs. It's only doable now because service is expensive and a recurring need. My model 3 needed service once in 2.5 years, for a minor warranty issue. Tesla doesn't make (much?) money on servicing cars. The only advantage of the OEM model is that there are a lot more dealerships than there are Tesla service centers, though it remains to be seen whether the current number of dealerships will be viable in an EV world. I doubt it.
As for your problems, I empathize, but most Tesla issues are resolved upfront, and then the cars are pretty hassle free.
