Today was a very interesting day at Perth Pre Purchase Vehicle inspections,today we went out to carry out a vehicle car inspection on a Mazda ,to begin with the car inspection was going very well until we carried out as part of the car inspection and TK gas test for a leaking head gasket and this test was positive to a leaking head gasket !! lucky this new car buyer took the time to have a vehicle inspection done because buying this vehicle would have been a big mistake
