Seven years after NBC4’s I-Team busted the one of the nation's biggest car repair chains, investigative reporter Joel Grover went back under the hood.
An insider told him: "If anything, it's gotten worse."
Two experts examined our undercover test car and said it needed no repairs or services other than an oil change.

Four locations recommended only an oil change, while seven locations recommended additional services. One location's said we needed services that totaled $697.
