Ferrari's first series sports racer, named for the marque's 1948 Mille Miglia victory — and winner of the 1949 Mille Miglia and Le Mans.
Powered by the 2.0-litre Colombo V12 and launched at the Turin Motor Show in September 1948, the 166 MM (Mille Miglia) was named in honour of the 1948 Mille Miglia victory taken by the Ferrari 166 S (Allemano coupé, Biondetti/Navone). The model itself went on to win the 1949 Mille Miglia, the 1949 Le Mans 24 Hours and the 1949 Spa 24 Hours; a 166 chassis fitted with the 195 S engine subsequently won the 1950 Mille Miglia. 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 | Not separately recorded | Definitive open coachwork; Mille Miglia and Le Mans winner. |
| 166 MM Allemano / Vignale | 1950–1953 | Not separately recorded | Smaller-volume coachbuilt coupes. |
| 166 MM Berlinetta Le Mans | 1950 | Not separately recorded | 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.
