Ford offered a more affordable version equipped with the two-barrel 351-cubic-inch (5.8-liter) Windsor V8. Customers who wanted more than 250 horsepower had access to the four-barrel variant, which delivered 290 horses. The options list also included the FE-type 390-cubic-inch (6.4-liter) unit good for 320 horsepower.
But unlike the GT, the Mach 1 was also available with the mighty 428-cubic-inch (7.0-liter) Cobra Jet V8. Offered in both Ram Air and non-Ram setups (Q- or R-code), the Cobra Jet mill generated 335 horsepower. While not quite as potent as the NASCAR-spec V8 in the Boss 429, it was the most potent mill customers had access to in the regular-production 'Stang.
High sales numbers also mean that first-year Mach 1 is quite the common classic nowadays. Sure, the Cobra Jet version is rarer at around 13,000 units, but it's a model you won't have issues finding. And it's not awfully expensive either.
That's not to say that some Mach 1s aren't very rare or unique. But that depends on features and the color combo. Sometimes, it takes a tiny item like air conditioning combined with an unlikely exterior/upholstery color match-up to turn a Mach 1 into a rare gem. This 1969 example in Gulfstream Aqua blue is a tad different because it flexes an option you won't find on any other Mach 1.
You won't notice it at first glance, but look closer, and you'll eventually see that this Mustang rocks a sunroof. Wait, what? A first-generation Mustang with a sunroof? You bet that's a weird feature because Ford did not offer such an option on the Mustang at the time. But a sunroof was available on the Mercury Cougar, and apparently, someone convinced Ford to put it on a Mach 1.
That someone is none other than Carroll Shelby, the man responsible for the cool GT350 and GT500 that turned the first-gen Mustang into a proper muscle car. And the story goes it's one of only two 1969 Mach 1s with a factory sunroof, so it's pretty much a one-of-one if we also factor in the options and the paint.
So what is the story behind this 'Stang? Did Carroll order it for his personal collection? Well, not exactly. Apparently, the car was specified for a doctor who took care of Shelby's mother. He asked if there was anything he could do for him in return, and the doctor requested a Mach 1 with a sunroof. Still working with Ford at the time, Carroll made some calls and turned the doctor's request into reality.
More than 50 years later, this unique Mach 1 is still around. And based on the way it looks, it went through a rotisserie restoration. It's spotless from every angle, and the Gulfstream Aqua color shines better than when this muscle car was new.
The blacked-out hood hides a 390 FE V8, so this Mustang wouldn't normally be as desirable and valuable as a Cobra Jet. However, that factory sunroof gives one-of-one status and puts it into six-figure territory. Hit the play button below to watch it sitting pretty at the MCACN show.
