It’s rare, but a seller could give you false details if they’re not the registered owner (e.g. a stolen vehicle) or if they don't want you to come knocking on their door if there are future problems with the vehicle!
Checking the seller is as important as checking the car!
Simply explain to the seller that it is no longer possible to look up the "registered person" without first entering their details. You're just being safe.
If they are unwilling to properly identify themselves then walk away; it's not worth the risk
