For those who take their car to Mercedes Benz of Naperville
Or any other dealership...If you are buying parts from them, go to parts.com and just buy it from them. I called various Benz dealers in the chicago area to ask for the pricing on the right side fuel pump assembly and everyone quoted me $1,224 + tax, including Mercedes Benz of Naperville. I went to parts.com ordered the same fuel pump for $800. I arrived next day from Mercedes Benz of Naperville, I even got a receipt from Naperville Mercedes except the reciept says "sold to: parts.com", and "ship to: My adress"
Its kind of funny becuase I could have bought it for like $1,400 directly from the dealer but I paid nearly $500 less just cause I ordered it online, from the same place.
