These Garage Bosses operate like drug dealers, dontcha know. Sure, you got a great deal, the first time. That's how it works. Next thing you know, you'll be hooked on their great, and honest service. Next thing you know, you'll be there once a week, begging for an oil change, or a tune up. Be careful. I sense this may be a "Gateway Mechanic," - leading to harder and harder repairs.
