You probably already know this, but backup cameras became mandatory in 2018. Backup cameras = screens on the dash.
If I could pick any Mirage, it would be the 2019 ES manual. Factory cruise control became standard for all Mirages in 2019, which I would like. In 2020, auto climate controls became standard for all again, which I don't like. Thus, the 2019 ES manual with cruise control & manual climate controls would be my first pick.
I could live with any of the three front ends of the Mirage. I see it as a cheap economy car, & the differences in front ends don't change my perspective.
CVT becoming standard for all Mirages in 2023 is a deal breaker for me, however. I would have zero interest in a new one now.
