sg_frost said:Under block exemption you must service the car using technically similar parts and should be stamped by a VAT registered garage. Now there is some arguments over whether they need to be VAT registered or not, and how you determine if they are technically similar. Mine will be serviced by myself using genuine parts and stamped at a garage that I used to work at. I am a qualified mechanic so they have no argument about that, but whether Joe public could get away with similar I dont know.
