You should contact the seller if there's third-party interest flagged on your vehicle. They'll be able to give you more information and if it relates to a finance agreement, they may be able to settle.
You shouldn't buy the vehicle until you've confirmed that no one else claims ownership of it. If you don't you could end up buying a vehicle that doesn't legally belong to you.
Why this check shows
This check shows if a third party has contacted us to register interest in the vehicle.
It means they're trying to track the vehicle's movement within the market to prevent it being sold on. Often, this will be because of a dispute over ownership or financial agreements.
We rely on third parties contacting us to flag an interest in a vehicle. With this in mind, there may be third-party interest in this vehicle that we are not aware of.
