I believe my Mach 1 has held its value in Virginia. I regularly see them pop up on Ford lots and they are priced near $50k. Which is nuts since they ran $60-65K new..
I had a 2022 GT without Magnaride, then upgraded to a 2023 Mach 1 with Magnaride. The GT rode like brick through broken up pavement, but I didn't mind the feeling. Both cars are used as daily drivers. The magnaride is definitely a smoother ride, especially if you are a 'seasoned' citizen.
I've had 3 new Ford Rangers (80,000 miles, 50,000 miles and 10,000 miles) with the 10R80 over the past 4 years. Also, one 2022 Mustang GT. No issues at all with any of them.
