Is this shop performing your oil change? You'd better check your oil dipstick afterwards; since they are known to add oil only to the *minimum* mark. Almost every OEM car owners' manual states when doing an oil change make sure to add oil to the "full mark" on your dipstick. Is this shop working on your brakes? Do not fall for the line: "you have a leaky wheel cylinder..." IF this is the case your brake pedal would of felt mushy and brake fluid should be visible on inner side of the tire rim and or on brake drum itself, so insist on them showing you the "leak." Are you having this shop install a catalytic converter and they want an additional $30.00 labor to install an oxygen sensor? FYI I called three other shops and was told: , "If we are installing your catalytic converter there will be no additional labor charge to install a new oxygen sensor. On most vehicles it takes under 5 minutes to install an oxygen sensor. Are you getting the jist of this review rating yet!?
