You are so lucky to have a family member or close friend who is knowledgeable about cars. I just had 2 rotors and all 4 brake pads replaced. I would have to check the receipts for the exact amount but it was approximately $700! Now, I have a son-in-law who is a very good mechanic and handyman although those are not his formal occupations. He is very busy taking care of their home and cars as well as working his job so I really don't expect much. However, he has never offered to do a thing for me! Snce I love my daughter and want her marriage to not suffer in any respect, i just roll with it, say nothing, and I try to act warmly toward him!
