Ouch. Yeah, he didn't have to do that - thankfully - we had originally planned to get it done at the place my husband always takes his car, so he knows one of the mechanics, but the day we had scheduled they were super busy and the mechanic ended up coming out and talking to my son and told him honestly that it was something he could do himself after they did the free inspection. I was floored by the guy's honesty, but I guess as busy as they were that day, they weren't too worried about losing the business that day. Besides, my h has spent a lot of money there in the past few years....
