Sorry to disappoint you, but, that isn't my experience - unless of course, the two cars that I recall being rejected were both imports or taxis - both were under 50k, one for sale at a VW dealership the other at an independent.They don't 'decline' based on reg.
It'll decline if you tick the box that says it's imported or used as a taxi or us a write-off and you'll get a limited product range if the mileage is more than 100k.
