I live in Washington too. I've owned many cars, including multiple Teslas between 2013 and 2024. I will tell you that there is no clear winner between direct sales and dealer system. At first (think 2013-2018) Tesla service was amazing, they would bend over backwards to help the early adopters, then then Model 3, and then Model Y came, profitability became the top priority and they wouldn't even cover a yellowing screen under warranty in a less than one year old six digit priced Model S. I saw people coming with videos of their Model 3's malfunctioning, and Tesla service saying "we cannot reproduce it, therefore the problem fixed itself". That is also when I realized that the manufacturer owned service service means there is no competition, so they can charge whatever they want - for example an $8 chip that failed in one of my Teslas causing the main screen no to boot costed $3,000 to fix (eventually there was a NHTSA forced recall, but not when I needed the fix, luckily I am capable of replacing a BGA EMMC part myself, but that is not within an average owner's capabilities). I now own dealer sold cars, and have to tell you I am getting great service from the dealer (4 cars, 3 different manufacturers), despite the manufacturer's inadequacies with modern technologies (yea, they suck at software). In the past I've owned many dealer sold brands, and my service experience varied. I've had some great experiences, and some horrible ones too. I remember long ago having an issue with a 2 year old Honda for which the dealer wanted a bunch of money to resurface the rotors, eventually getting new rotors replaced under Honda warranty, the service guy literally winking at me saying "hey, I gotta try to make money, eh?" (yep, he was Canadian ;-) ). On the other end of the spectrum I had a Lexus once which the dealer was willing to go to mat for me to lemon my car over a bluetooth hands free issue that Lexus (Toyota) was unable to resolve. Lexus actually sent an engineer from Japan to repair the problem (turned out to be a bent pin in one of the harnesses) tp avoid the car getting returned as a lemon.
Bottom line is that direct sales vs. dealer experience does not have a clear cut winner for consumers. I do however strongly believe that both should be allowed by law. This explicit allowing one manufacturer at a time political bribing shit in WA state is just government corruption (happens in other areas to, check out automatic card shufflers allowed in WA as an example, or charter school licenses). I say let people choose, do they wan to buy from a dealer or direct from manufacturer, let he market decide what the people want. Heck, allow the same manufacturer to sell via dealer and direct, see what people choose. I bet such a choice would spurn competition for dealers to show people why it's worth it buying from them. And yes, I get that it would cost some dealers profits, in situation where they require people to buy a bunch of their cars to qualify for an allocation for a special car (e.g. Porsche 911 GT3 RS), or charge Additional Dealer Markup on top of MSRP (e.g. Corvette).
