Better yet, just stay away from all National chains for repair work. Find a good independent mechanic with recommendation from older friends or the Mechanics Files on this forum. Once you have built a relationship with them you will be amazed at how much unnecessary work you were having done. There are so many redundant charges on that list from Firestone that it should be criminal.
I went into our local Firestone store a number of years ago and the manager lost all the color in his face when I walked in. It seems that I was a dead ringer for an investigator for our states Attorney General’s Office that had visited him before.
