It's actually kind of funny that I have experience with that California dealer. Make no mistake, if you show up in person, they will do all the same nasty tricks that most dealerships will. However, for some reason, it seems like they have an
abnormally good online division.
You send them a request online; they send you a pretty good, but not great, offer via email with no hidden garbage and no irritating attempts to pull you in in person. You go in, and they see if they can run the financing through themselves and shrug if your financing is better. You sign paperwork and drive off with the car.
3 people in my circle of acquaintances bought cars from them simply because their online presence is so pain-free.
They must have decided that running low touch, higher volume through the online pathways is a better choice. Presumably online buyers fall into 1) will waste your time grinding you down, so sending an offer and being done minimizes the time wasted and 2) wanting to interact with people as little as possible so those customers will bite at a good offer with a bit of profit baked in as long as you don't make them deal with people very much.
