Why is vehicle identification the most difficult and time-consuming task faced by an investigator in an auto theft case?

Vehicle identification is challenging for investigators in auto theft cases due to the prevalence of vehicle cloning and the alteration of identification numbers, such as VINs (Vehicle Identification Numbers). Thieves often strip or modify vehicles to conceal their true identity, making it difficult to trace ownership. Additionally, the sheer volume of stolen vehicles and the need to cross-reference various databases can be time-consuming, complicating the identification process further. These factors combined necessitate meticulous investigation and verification to establish a vehicle's true identity.
