Likewise. I hate car dealerships. For my wife though, it's a whole other thing for her. She's typically a very reserved and private person...until she walks into the dealership. She somehow enjoys the combative sparring with after finding the slimiest, sneakiest salesman in their organization.
When we bought the Prius in 2015 we were there for about six hours total, at least four was directly negotiating with the salesman. I can't blame her, because she was good. Sticker was $26,200 and our out-the-door price with all fees included was $21,300. Yes, that also included floor mats, Scotchguard bullshit treatment on the seats, VIN window engraving, a car wash kit, and a cool key chain (that I never ever used). I didn't care about any of the other bonuses thrown in there but I think the salesman legitimately could not go any lower on price, so he actively started offering extra stuff, probably to get us the hell out of there.
No dealerships with a Tesla purchase experience means no negotiation, and I'm glad. Secretly my wife is probably glad about that as well. On the other hand, for customer service, vehicle service, and warranty-related affairs, not gonna lie, I'm really skeptical.
