you could create a plugin to check the VIN number.
it is just a suggestion. maybe it is feasible to create this plugin.
1. integrate several VIN checkers. make it compatible for use in asia, europe, and latin america.
2. integrate it with osclaspay
3. offer pack for users.
4. set a limit.
5. the option to choose which category to activate it.
6. offer the service or a button on the page to add an ad. if the user pays, the user will be able to enter the VIN and fill in the fields automatically.
7. if a user gets the service, on the ad details page hide it.
8. offer a button in the ad details to check the VIN number but the user must pay to see the vehicle data.
to avoid misuse of the data.
9. users must be registered to use the tool.
these are suggestions. maybe it is possible to create it.
Maybe it is possible to improve it with other ideas.
thank you. best regards
