When I sold my last car the buyer had it inspected at BD4's in Sydney. They did a pretty good job, not sure what they charged but went right over the car, engine, drive train, you name it. Getting it done at a workshop meant they could put the car on a hoist and the mechanic also drove the car with us in it to test it on the road. Verdict.
"mate cars in good nick apart from being BLOODY LOW"
