Hi Derek.
We know of them at the Nano meets, as we found out that the owner got a few friends to slowly bring his cars to the Nano to get them health checked on the T4, have options changed etc left right away to go & get another this went on for a while until they got found out, had no intentions of helping out anyone else just out for gain on their own behalf.
Basically he was using the Nano for fault finding sometimes getting the car sorted so he could sell it on, also he had a captive audience to try and sell the cars too
