Sure but C8 buyers will happily pay more, aggressive, increases, its that much of a hot ticket item and GM could get away with it.
The 5BW is much less production but a 10% increase in the base price is pretty nuts, either GM screwed up with the original MSRP or the car its made out of highly sought after carbon fiber goat grazed microchips. A 10k increase on a 90k car is pretty ridiculous, I use the C8 as an example of a vehicle that is highly sought after and has only had small little increases, GM could easily milk it for more but the 5BW getting such a large increase is pretty crazy, even in todays world.
It is what it is but the only cars that had that much of a price increase between the '22 and '23 model years are vehicles that cost 1.5x+ as much. Even the 911 "only" had like a 6k price increase but it starts at 30k more then the 5BW.
I know the 10k is Canadian pesos but even in the states the 7k increase is pretty significant on a car that started in the mid 80s. I still think GM screwed something up with the original MSRP (it was comparable to a 3rd gen CTS-V which is pretty remarkable) or something in the car became much more expensive compared to other vehicles. The Camaro ZL1 which shares a lot of parts had a decent price increase as well but even it was about 5k Canadian compared to the 5BW 10k, I beleive US price increase was 3.7k? So maybe its related to the LT4.
Either way for a manual supercharged V8 sport sedan, the increase is still worth it, but whoever got a '22 is laughing.
