Maybe it's painted by mistake in factory?
You can expect such things.
If the people at toyota says it's okay.
Plus go to 15 police office in lahore and verify. Also visit the excise office though there is online record on website too but for your own satisfaction.
You really don't need to know that why it's painted or how. You have documents and different ways to verify such things.
Just do these things and move on.
And please don't follow the local painters.
Theives nowadays sell cars in balochistan and kpk in areas where no one ask you or stop you or they simply sell the cars in parts or they will call back the owner and demand some amount and give the car back. Those days are gone where you can sell the car by making fake documents and chassis plates which can be verified in seconds.
