Forza Motorsport 2023 has two NA Miata’s now, the 1994 1.8 car and the 1990 1.6 car. The devs went through the effort of making different engine bay models and other changes, but the interior in the 1990 Miata is incorrect, as it has a different dashboard than that of the 1994+ 1.8 cars. The 89-93 Miatas don’t have the passenger airbag or the curvier dash. Literally one google search would tell you that.
