🚨 Avoid Retrofit Frauds:Always decode the VIN configuration rather than relying on visual trims. Some sellers fit visual replicas (such as speaker covers or AMG body panels) on standard vehicles to charge a premium. A genuine datacard decode matches the vehicle's manufacturing specifications on the day it rolled off the assembly line.
