I took my BMW to courtesy motors in Chico for a new clutch and clutch slave and clutch master after the clutch would chatter and sometimes not disengaging. I peaked under the car today and it looks like the trans has never been out but the clutch hydrolic parts have been replaced. But the bolts to the block looks like they have never had a wrench on them but yet I was billed for a new clutch set and the labor. What do you guys think? I feel I have been taken as the bellhousing looks like it has never been seperated from the block with the dirt and crud on it.
