Brother you are mistaken. the poor did not benefit a lot, though they did to some extent.
The major beneficiary in this whole game were
- The smugglers, they sold their cars for way higher than these were actually worth
- The corrupt judges who gave absurd decisions and took took bribes for doing so
- The lawyers who form an important part of any court case and charge quite heavily from all the complainants or appellants
Coming to your question
Check all the documents related to custom clearance. These include a clearance letter from the custom collector, a challan form for depositing of the duties, a delivery order from the custom authorities and NOC from custom authorities to get the vehicle registered. In addition there should be a clearance letter from 15 and Forensic lab test report confirming that the vehicle is neither a stolen one nor is tempered. All these documents should be available in the returned file. Of course the original book and number plates are very important too.
