I bought stainless steel brake lines and performance brakes for my car, and called Dean to see if they could install them along with my usual alignment, rotation, and oil change. They said normally they don't install third-party parts, and certainly wouldn't provide a warranty on them, but I said that's fine - I just needed someone to put them on. They scuffed up the existing rotors for the new brake pads and installed them. The quote and cost of labor was transparent, and they communicated the status of the car well. A trustworthy mechanic is what I wanted and they treated me well.
