By 1969, the Ford Mustang was arguably the most popular and recognizable car in America, and Blue Oval executives knew it. Ford kept rolling out new engines, options, and packages for the pony car, and 1969 was option package peak for the Mustang. Mustang buyers could choose the GT, Mach 1, or BOSS packages that added all sorts of stickers, performance parts, and premium options that few buyers could turn down. And that’s not even including the Shelbys!

So what makes this particular Mustang so special is not what packages it has, but rather what it does not. Ordered with the 428 cubic-inch R-code Cobra Jet V8 and an automatic transmission, this non-GT, non-Mach 1, regular ol’ Mustang is heading to Mecum’s Dallas auction this weekend. How much it will bring is anybody’s guess, but this unique Mustang could be worth more than its premium-optioned peers.

The fastback ‘69 Mustang came with Ford’s top-of-the-line engine option, the $420 428 R-Code Cobra Jet ewith the Ram Air Shaker Hood option. That engine is backed by a Cobra Jet-spec C6 automatic transmission and a Traction-Lok rear differential, on its own a $64 option. Other options included power steering, power brakes, and a factory tachometer and suspension package separate of the Mach 1, GT, or other pre-packaged options from Ford.

That means no extra stripes, no extra badges, no extra louvers, though the non-functional side vents are still there. This clean-, well-kept Mustang would normally fetch between $70,000 and $80,000 at auction with a GT package and the big-block V8. But because it is so unique, non-descript, and clean, the price for this unique ‘69 Mustang could cross into the six-figures. How much would you lay out for a plain ‘69 Mustang with a monster motor?
