There are a few reasons for the poor BRZ sales. 1st is the internet's untrue hysteria. The rumor is the engines explode for no reason. You can't make right-hand turns and the RTV in the oil pan is going to make the car explode.
Sales started off very strong then the panic struck. Add in the fact that the selling point of the BRZ was that it was one of few modern vehicles that was very analog. Subaru screwed that up and put Eyesight into the newer models even with the manual trans cars. That ruined it for a lot of potential buyers. I will hold on to my 2022. It is the last of the good ones.
