Q: I own a american spec. BMW 325i 2002, but I want to purchase the parts cheaper than what the auto shops are charging.
A: FWIW, in order to preserve brand ideals, dealerships are made to sell high. It's not unusual - many high end brands distinguish their clientele using price mechanisms. GOOD for BMW - and car enthusiasts - that their cars can perform better than garden variety brands. BAD, because money does not guarantee a better driver - and these cars are not meant for fuddy duddies. ANYWAY the answer is, look for niche workshops, run by ex-dealership mechanics. You should be able to find a fair price from these guys. Also, because their reputation depends on their overall quality of service, they should do what it takes to maintain their reputation. For bargain basement prices - there are 2 choices - at one's own risk. Online stores (ebay) and salvage yards. Hope this helps.
