Just noticed on the front of the site there is a quesiton about a NMR (National Mileage Regsiter) and WeBuyAnyCar telling a seller their car is effectively clocked.

HJ's answer isn't quite correct in my view on this. The NMR does not in fact usually record MOT mileages. It records keeper changes where the mileage is entered on the V5, servicing mileages from some manufacturers, some information from leasing companies, finance houses etc., results of it's own investigations and most importantly the mileages entered when a NMR check is done.

The vast majority of errors seem to come from the latter source. For example, last week I did a NMR check on an Audi which had done 155k. I accidentally entered two letters the wrong way round and it came up as a Vectra. That Vectra now has 155k recorded on the NMR check and anyone else who does a check will see it.

This sort of thing happens all the time. NMR is a useful product, but they are just a commercial organisation, an error on there does not immediately mean a car is clocked - they are not gospel on the subject. Obviously if there is a pattern (10 recorded increasing mieages then one big drop followed by more low entries) then common sense says it probably is clocked but you need to interpret the data.

NMR will usually delete one anomoly if you talk to them, particularly if from a non-verified source. WBAC in this case were just trying it on IMO and the car probably isn't clocked at all.
