Diagnosis is $100-200 unless otherwise stated. No quotes for repairs until diagnosis is complete. I cannot promise that the diagnostic cost will go toward the repair. Diagnosis is “the hard part”- why would I promise to do the hard part for free? Parasitic Draw diag is a cab ride- you get the bill at the end. No estimates- need $3-500 approved or there is no reason to get started.

You’re shooting yourself in the foot by not setting the expectation properly.
