So we have a 73 Mach1 that my wife bought new in June of that year, she drove it to work, hauled kid to school and just enjoyed it. We finally were able to get a second car so it got to sit and be used for fun things. Imagine though in south Florida a Mach1 with no ac no power steering and no power brakes! But we were a lot younger and stuff like that didn’t matter. Years go by and it’s never been painted but has had dents dings and minor damage in its 67k miles. I being a mechanic couldn’t help upgrading under the hood but engine and transmission are still Oem. Hopefully we can help others with information and knowledge. Looking forward to posting our Elite Marti report. She is for sure a different Mach1 unusually equipped as the Mart report says it is the only one on record equipped as she ordered it.
