Both the IS300 and IS350 saw some pretty significant changes in 2019. As a result, there was not much that needed updating in 2020. There is, however, a Blackline Edition package that makes the IS even more stylish. It adds darker exterior accents to places like the mirror caps, grille, and wheels. Inside, drivers will find many dark blue door panels, dashboard, and steering wheel. Completing the look is dark blue and gray accent stitching.
