GTA production numbers were down severely for 1990, due in part to the early introduction of the face-lifted 1991 models in the spring of 1990. The ever-escalating price tag could have had some effect on sales as well. Still, the GTAs came fully equipped for battle again for 1990, and represented the ultimate Firebird model. Once again, the RPO logs kept track of GTAs sold in the US, in Canada, and those built for Export sales.
Below are the production option breakdowns for 1990:
