It's not a Mach 1. They were only available as a SportsRoof (fastback). However, it's real common for owners, like the one who had it before me, when the car gets repainted, to add a front spoiler and Mach 1 stripe to their car. That was the case here. The bright yellow is a great color, but I'm partial to Bright Red.
It's also unusual in that it is has the 250 cu. in. inline six. Only 723 convertibles built with a six that year. I was looking for a red one with a six and this is what I found a few years ago. Most that are left have had the six swapped out for a V8. It's also unusual that for 1973, all convertibles came from the factory with power front disk brakes standard, even with a six.
I'll be all Ford for the first time in my life, and fit easily in both. The Toyota and the Volvo are for sale.
