Authenticate stamped chassis, engine and body numbers against Maserati Classiche records in Modena. For the Sebring specifically, verify the exact series (Series I 3.5 or Series II 3.7 / 4.0) and treat the production totals as approximate.
Confirm body originality, coachbuilder identity (where applicable) and restoration standard against a Maserati marque specialist.
Confirm continuous service history and any rebuild history for the engine, gearbox and driveline against a marque specialist.
Restoration standard, originality of body and driveline, and any documented ownership record are the main value drivers.
