Time Capsule 1973 Mustang Mach 1 Is a Four-Speed Cobra Jet Unicorn, First Owner Sold It in 2023

The volume was split across four distinct body styles: 51,480 standard hardtop coupes, 25,274 luxury-focused Grande coupes, 11,853 convertibles—the final year for the factory-built drop-top—and 10,820 standard fastbacks.

Standing firmly apart from the standard lineup was the Mach 1, which was sold exclusively as a fastback (SportsRoof was the official designation). With 35,440 units produced, the Mach 1 served as the performance anchor for the range. While buyers could select from several engines, the "Q-code" 351-cubic-inch 4-barrel (4V) Cobra Jet V-8 represented the peak of the 1973 performance hierarchy, with 259 hp and 292 lb-ft (net figures).

The rarity of this specific car is underscored by the era’s shifting preferences; the overwhelming majority of the buying public opted for automatic transmissions, making the combination of the Q-code V-8 and the four-speed manual transmission a remarkably elusive find for collectors today.

This particular 1973 Ford Mustang Mach 1, offered on eBay for $46,500 by a dealership (awesomerides is their alias on the online platform), is a genuine time capsule that captures this final, heavy-duty era of the first generation in its most authentic form. With an odometer reading of just 40,004 original miles, it has been preserved in a garage under the care of its original owner for over half a century, only changing hands in 2023. 

Unlike many of its peers that were subjected to the inevitable cycle of modification and restoration, this car remains an undisturbed survivor. It still retains its original factory stickers, assembly stamps, and even an unmounted spare tire that has never touched the road, appearing exactly as it did when it departed the Dearborn assembly plant.

The car’s extraordinary condition is fully authenticated by a wealth of original documentation. This includes the owner's manual, original warranty papers, and a comprehensive Deluxe Marti Report that validates its factory-correct build. there's and even a dealer jacket from Key Ford in Evansville, Indiana, that authenticates this time capsule.

Finished in Light Blue over a black knit vinyl interior, the vehicle remains remarkably intact. It is equipped with desirable options, including SelectAire air conditioning, power steering, and power front disc brakes, offering a perfect balance of period-correct comfort and the raw, mechanical performance of the 351 Cobra Jet engine. 

Rather than a candidate for restoration, this Mach 1 is a turn-key classic for the collector who prioritizes absolute authenticity over cosmetic perfection. It displays only minor, expected paint touch-ups consistent with its age, serving as a testament to its status as a real survivor.

For the enthusiast seeking the visceral, analog experience of a final first-generation Mustang in its purest form, this Mach 1 stands as a superlative find. There are still 23 days left for prospects to meet the owner's asking price (unless someone uses the Buy It Now option earlier).

The current seller most probably acquired it last October, from the Mecum Indy Fall Special auction, where the all-original pony hammered for $40k ($44,000 paid by buyer with 10% sales tax). The odometer accumulated just ten miles during this time.

Notably, in May 2025, at the Indy event (also hosted by Mecum), this automobile got a high bod of $40,000, but reserve was higher than that final offer.  All in all, the current seller is looking for a $2,500 profit, so this gorgeous survivor isn't the typical flip scheme we see way too often.
