chuck up some interior pics. with roadworthies i think the best thing to do is get a consultation- what's wrong with the car for the test from a tester, then having told them you're getting it at someone else go to the next tester, get a second opinion and do it. what would happen is that the tester usually a mechanic would try to screw you over if you just went with them for the consultation and the test. i find that the best thing to do is to go a local mechanic for an older car i.e pre VT because they're bound to have faults somewhere and for a newer car like a VY that's been off the road just go to bridgestone tyres or whatever
