ACA fundamentally does a good job in many areas that count with regard to general overall practices that matter such as personable customer interactions, follow up phone calls and a rather efficient work flow. One thing that I did not appreciate was an arbitrary non-written or posted policy of a 20% labor increase upcharge for customer supplied parts. The term used was "it's like bringing your own steak to the restaurant ". I dont agree with practice from a customer relations standpoint, in my opinion it may be favorable for the shops bottom line, however unfavorable for customer retention and future return business and potential referrals. Overall it's an age old "policy" that leaves a lingering bad aftertaste to an otherwise reasonably good experience.
