Just a thought regarding availability.
It's a well known fact that plants, when they start up, go through an acceleration period.
We also know that the yearly volume of the solstice is somewhere around 20,000 or 25,000 at full line rate.
That works out to between 1600-2000 cars a month.
So the question is whether we really know the real startup date (May 16? Delayed? Week 19 or 20?), which is up in the air. Let's just go with the original speculation from the early information and call it "Mid-may".
If they take, say, 4 months to ramp up production (don't know if it's 4 months, 4 weeks, or a whole model year, I'm just guessing here - it just seems reasonable for a brand new car and platform) - then by mid-september they should be at about 1600 cars/month.
Linearly, that's a rate of 400/mo at mid-june, 800/mo in mid July, 1200/mo in mid august, and full production of 1600/mo in september.
Integrating (remember THAT, engineers? - area under a rate curve? A linear rate function is triangular, therefore 1/2 base [1 month] times height [400/month]) that function is basically the 1/2 the current month's rate X # of production months.
That would work out to "theroetically produced volumes" of 200 by mid-june, 800 total produced mid July, 1800 total produced in mid august, and 3200 produced by mid- september.
Tack on 2 weeks delivery - and you can change the months by one.
Problems with all of this, while it's a very interesting look at what might be happening:
-We don't know the real start of production date.
-We don't know the intended production acceleration
-We don't know if the acceleration is linear
-We don't really know the true monthly production rate
-We don't know the true shipping date.
A significant error in any of these, and, while technically production might start on time, it may well be September before we see any of these cars. From a dealer standpoint - to them the car won't be available until Fall.
Just going by this example, the first 1000 will take up at least the first 6 weeks of production.
Interesting math games. Play with the numbers yourself and see what makes sense.
