I think this goes without saying for car dealers in general. My experience has been similar at Newport Beach. The sales person seems nice enough, but schedule info has been vague and they have not gone out of their way to keep me updated.
They really should have let you know about the display this week - I at least got an email inviting me. Was there a presentation? I just showed up and they found a guy to answer a couple questions for me. Didn't see any presentation.
My delivery estimate has been delayed now to after Christmas. I also specifically requested delivery before year end; at this point, I'd give it no more than a 50-50 chance. I was also told they expect to have I-Pace available for test drives in October, though I don't put much stock in that, either. Like you, I'd like a nice new EV, but I don't expect anything comparable to be available for at least a year. I guess I could still go for a Model 3, but Tesla Corp. seems like it may be falling apart now. Or a nice ICE car. Or just keep waiting...
