| Variant | Years | Production | Notes |
|---|---|---|---|
| SM 2.7 (carburettor) | 1970–1975 | 12,920 total | Maserati 2.7 L DOHC V6; DIRAVI variable-assist self-centring steering; hydropneumatic suspension; FWD; ~140 mph; 5-speed manual or 3-speed automatic. |
| SM 3.0 / fuel-injected | 1972–1975 | part of total | Later 3.0 L and fuel-injected cars; the sought higher-spec variants. |
Authenticate stamped chassis and engine numbers against factory or club records. For the SM specifically, verify Maserati V6 service history (timing chains and top-end care are decisive), confirm hydropneumatic system health and identify carburettor versus fuel-injected specification.
Confirm body originality, panel identity and restoration standard against a marque specialist.
Confirm continuous service history and any rebuild history for the engine, transmission and driveline against a marque specialist.
Restoration standard, originality of body and driveline, and any documented ownership record are the main value drivers.
