The Meccanica Maniero 4700 GT (chassis MMGT01) is the kind of object that doesn’t sit in the “normal” classic-car market. It isn’t a rare version of a known model—it is a true one-off prototype. The concept began from a practical frustration: an Italian businessman wanted a high-performance GT that was easier to live with day to day after struggling with the low exhaust clearance of his Maserati 3500 GT. He commissioned Giovanni Michelotti to design a compact, assertive coupe that blended Italian style with American V8 power.

The car is described as being powered by a Ford 289 HiPo (4.7 liters) rated at 275 hp with solid lifters, paired with a four-speed manual gearbox—specs famously associated with the Shelby Cobra. On a short 2,400-mm wheelbase and a stated 1,450-kg curb weight, the recipe promises a responsive, usable GT rather than a pure showpiece. However, there is an important technical caveat worth spelling out: a close-up photo shows a “Ford Industrial Engine” identification plate, with a type code that includes “6001” (Ford’s basic part number for the engine assembly) and a prefix that appears consistent with Ford’s industrial-engine channels. That plate, on its own, is not evidence of a “HiPo” in the strict, collector sense—if anything, it is more consistent with an engine assembled and sold by Ford for industrial applications (generators, pumps, machinery), or a later crate/industrial replacement installed at some point. This does not automatically mean the engine is not a 289, nor does it rule out HiPo-style components, but it does mean the “289 HiPo” claim should be verified through block and head casting numbers and the specific K-code identifiers, rather than accepted purely on narrative.

The prototype debuted at the 1967 Geneva Motor Show and, according to the story, Scuderia Filipinetti’s Georges Filipinetti was impressed enough to propose an order for 50 cars. The Maniero family never pursued production, leaving MMGT01 as the only example built. Its subsequent life follows the same private logic: it remained with the family for decades before being acquired in 2016 directly from them by a collector focused on preservation. The presentation emphasizes original finish and the visible tonal variations in the paint, along with a period-correct cabin featuring Jaeger instrumentation and an unmistakably hand-built, prototype atmosphere. One of the more interesting aspects is its transition from “kept” to “usable.” The car was never road-registered by the Maniero family, and it is said to have been mechanically recommissioned under current ownership to ensure proper drivability while retaining originality. It is now road-registered in Belgium with the personalized plate MMGT01 and shows just over 6,400 kilometers. In short: absolute exclusivity, a coherent backstory, and a concept that merges a major Italian design name with American V8 performance—plus one sensible technical question to resolve, because the presence of an “Industrial Engine” plate leaves open different scenarios about the exact origin and specification of the engine currently fitted.
