So they put a vehicle on the rack and the alignment was within specs (all good) and you are saying that they still charged the customer full price??
If not, then that is called an alignment check…
I had a Mustang come in on the hook with a tire blown out from a pothole, it needed 4 tires anyway and had uneven tire wear, I sold the customer 4 tires and an alignment up front, well once it made it to the alignment rack and checked we found the alignment to be in specs, almost perfect… I down sold (GASP) from an alignment to a free alignment check… Should I have ripped the customer off and charged them for something not done???
It is not window shopping if it does not need it… Now I agree that just doing an alignment check for the heck of it is about useless…
