let me clarify things a bit, the cost that is quoted by 3s is usually the maximum cost. They quote you high because once the car is opened up, only then they can confirm what needs changing. Secondly they only go for replacing the part not repairing it plus the parts sold by 3s are somewhat higher in price. So basically they are not ripping you, its how it works. Honda 3s quoted me 80k for suspension work, yes its high but he said that this is the max cost, otherwise once they open up the suspension only required parts will be changed so actual cost can get lower.
Honda 3s replaced me a power window switches unit for free (worth 12k) hows that?
