You story is not unuual. It’s common for hard to find cars to sell for much more than sticker.
It’s called supply and demand. And I don’t agree with you that the dealer was a jerk.
Years ago when the Chrysler PT Cruiser first came out, they were selling for 25 to 30 thousand bucks. Yes they were.
Ten years later - at the end of production, you could have bought that same car for $17,000.00
Anyway, back to your Camaro story. Everyone knows you don’t buy ANYTHING when it’s first released. Especially a car that is in limited supply. Just be patient and wait - the prices always fall.
The Genesis I bought had just been released too, no mark up.
I know about the mark ups on hard to get vehicles but to me 10K over sticker on a 35K mass produced vehicle was out of the park...a few more grand and there were Corvettes aplenty available.
Anyway that was then, now I am considering moving up 3 model years on my current vehicle without much luck in dealing. Plan to wait as you suggest, perhaps by June the market will be different on the 2013s.
