Aye, I've dealt with Ford and Mazda dealerships that were utterly abysmal. Others were better. Hit or miss quality of dealerships and service centers is not a surprise and not a flaw of the brand per se.

"But Tesla is a luxury model that competes with Porsche and should make me feel fancy and be super nice etc etc" ...eh kinda, but not really, IMO. The S model does but future models are aimed at a more down-market segment and are going mainstream.
