Should I be able to buy Genuine Acura parts for a timing belt/water pump replacement from one of the dealers who discounts parts and bring the parts to my dealer to have installed? Would your Acura dealer allow you to do this or do they require that you buy the parts from them? My local dealer quoted me prices over list for the parts. I can save about 35% having the parts shipped to me first. Is it worth asking to bring in my own parts or would I offend the dealer?
