Part of the legitimate income for an automotive repair facility comes from the selling of parts. There might well be an adjustment in the labor charge to off set this loss in the case where the customer brings in his own 'steak and eggs' and asks the shop to cook them. Where we run into difficulty with this scenario is in who pays when something goes wrong with the part or in the customer derived diagnosis? Warren Anderson Sedona,AZ
