Now, I find this to be a fair point to have a discussion about, and mostly agree with you on this. Where I disagree, is that it can still be pretty different at a regular car dealership. If someone "puts in the work" they can arrive at "similar pricing" at a regular car dealer, that much I agree with.
Everyone buying a new, ordered, tesla pays roughly the same price if they are picking up the same day as someone else. Buying a car "in inventory" or a "dealer demo" or something like that skews things, just like it does at other car dealers.
The biggest difference with Tesla and other car purchases is, if I order a new tesla in CA and pick it up a week from now, someone ordering and buying the same build in Oklahoma will pay the same price if they pick up the same day I do. Most car dealers now have regional programs, so (for example) BMW incentives in CA are different than BMW incentives in Oklahoma, or New York.
But yeah tesla does do incentives sometimes, to move inventory cars just like other car dealers. Tesla "salespeople" say stuff to move cars that is sometimes incorrect, just like other car dealers. There is no promise that a discount on the car wont happen the day after you drive it home, just like other car dealers.
The only part of a tesla transaction that is different is that the pricing on ordered cars is usually the same at a specific date and time across the nation, and its "easier". You dont have to do research to avoid getting ripped off.
Otherwise, its a regular car transaction, with all the pitfalls of one.
