Service advisor kept me informed of status of repair and what new repairs were required. Overall good experience but I have the following complaints:
I was charged double for diagnostic than what I was told it would be and had to point it out to the advisor.
There was a battery special that they did not automatically give me. I had to produce the email with the discount to get it. Would have liked them to give me the advertised special without having to ask for it.
Word to the wise. Check your bill and check for the specials so you don t overpay.
