I was buying when there wasn't this mix of limited availability + buyer insanity
When I ordered my Z06, it just got put in as an order and moved through the system as expected.
I guess maybe I'd get onto a list now, with some low deposit ($1K or less, an refundable would be nice), and just figure by the time your option comes up to buy/order, you'll be in a position to do so (i.e., it'll be a few years).
That being said, I suspect, given the price (including insurance, consumables) and usability (2-seater, RWD, limited storage), the market segment is pretty small. It's pretty much in the "old retired white guy" price range at $100K or more, I bet there's a surge for about 2 years - you know, assuming they are able to build them at full capacity (I saw something about the first model year being limited to about 500 units[?]). Then a reasonable availability (with that assumption) starting in year 3 or 4 - so I suppose if you're at least 4 years out, being on an order list might not even be necessary.
