I thought they have been saying that all trim levels will be available spring of 2024? They may not make that exact timeframe but they at least seem to have a goal of having all trim levels out from the get-go (or at least after the special first editions next fall). Most companies that lead off with the high-profit trims are up front about it. So why would GM want to take the negative publicity hit of not following through with the overall plan?
Yes, that's what I have seen as well. His theory is Chevy will just refuse to make many of the entry level price point cars. So even if there are 100,000 orders, they will only make 10,000 or whatever. This is what Musk did with the model Y. He sold a few at $35k and then poof, no more. So I think a Tesla fanboy would naturally think GM will do the same and any claims to the contrary by GM must be wrong.
On the other hand, maybe GM WILL prioritize the higher priced levels in some way. As a business it does make some sense. Perhaps it will come down to supply chain once again. If there is a shortage of battery raw materials or chips...
Maybe my Musk-bias is showing.

Ever since he bashed the Volt for having a gas engine and has been consistently wrong on release dates, etc. I have soured on the guy. At one time he even claimed his production line would be moving so fast that wind speed resistance would be a problem, lol.
Anyway, we will see if Chevy's "all trim levels" claim is true or not.
Regarding the Bolt EUV, One car does not fit all. GM having a broader selection of EV's from Hummer to Silverado to Blazer, to Equinox EV is a good thing. And of course Cadillac Lyriq, and whatever Buck comes out with. More options to fit your needs. I could swing a Lyric, but as a cheapskate I have a hard time parting with my $$$. I'd rather the $60k+ sit in my retirement account.
