The Simplest Solution would be any genuine owner will usually have the car under his own name and dealers have multiple cars they usually avoid having cars on their own name due to tax and cost issues.
1st Owner Cars with the seller being the 1st Owner solves your problem but such cars are rare to find.
Interestingly I know many dealers and part time investors who pretend to be genuine owners but are just resellers emanating that they are genuine sellers selling their personal car parked at their homes.
But not much can be done by Pakwheels regarding that.
