Ferrari's first commercial road and race car — and the car that won the inaugural Mille Miglia, Le Mans and Targa Florio under the Maranello name.

Powered by the 2.0-litre Colombo V12 and built in extremely small numbers between 1948 and 1953, the 166 MM (Mille Miglia) won the 1948 Mille Miglia, the 1949 Mille Miglia, the 1949 Le Mans and the 1949 Targa Florio. The lightweight Touring-bodied barchetta is the definitive shape; a smaller number of Allemano, Vignale and Stabilimenti Farina coupes were also built.
Accurate production figures vary by source; widely cited counts sit between 25 and 50 chassis across body styles.
Ferrari's foundational racing road car and the chassis on which the marque's earliest international race wins were achieved.
| Variant | Years | Production | Notes |
|---|---|---|---|
| 166 MM Touring Barchetta | 1948–1950 | — | Definitive open coachwork; Mille Miglia and Le Mans winner. |
| 166 MM Allemano / Vignale | 1950–1953 | — | Smaller-volume coachbuilt coupes. |
| 166 MM Berlinetta Le Mans | 1950 | — | Closed coachwork derivative. |
Start with identity, paperwork and originality. For the Ferrari 166 MM, the strongest cars have continuous ownership history, matching numbers where applicable, original books and tools, factory build documentation and evidence of work by manufacturer-approved specialists. Period race history, body-builder originality, completeness of chassis records and Ferrari Classiche certification.
The early Colombo V12 is supported by senior Classiche specialists; period correctness of components and stamping is paramount. A proper pre-purchase inspection includes cold-start behaviour, ECU diagnostics and fault-code history (where applicable), leak-down or compression testing, underbody photography, suspension and chassis inspection, brake condition and a long enough road test to expose heat-related faults. Deferred maintenance on a car of this class is almost always more expensive than buying a better-sorted example.
Use a paint-depth gauge, lift access and a specialist familiar with the model's factory panel gaps and finish standards. Collector value is dramatically affected by structural repairs, refinished panels, poor paintwork and missing factory trim or option content. Documented cosmetic refresh is acceptable; concealed accident or fire damage must be priced severely.
Touring Barchetta cars with period racing history lead. Continuous ownership and complete chassis records are decisive. Specification, colour, options and limited-build variants move values significantly. Buy the best-documented example in the most desirable specification you can justify, rather than a tired example of a rarer derivative that will need years of corrective work.
Regional ranges authored independently — each reflects its local market, not an FX conversion
Budget annually even if the car is used sparingly. Fluids age, tyres and date-coded rubber components must be replaced regardless of mileage, and stored cars need exercise. A documented maintenance rhythm protects both reliability and resale value.
Service and inspection at this level are conducted by senior Ferrari Classiche specialists with documented 166-era experience. Before purchase, confirm parts availability for model-specific bodywork, electronics, gearbox and engine components. A discounted car waiting on unobtainable parts or a factory service slot is rarely a saving in collector ownership.

166 MM chassis transact rarely and primarily privately. Publicly known auction results in the last decade have ranged from $7m for less-distinguished chassis to well above $12m for race-history Touring Barchettas.
