Good parts. I was a little surprised by the part numbers, as they did not match the mercedes numbers that I used to order. When I went back to the original mercedes part, it has the same Beru numbers that match. Therefore, I believe it is an exact replacement, though it does not have the mercedes numbers.

tried to use paypal but wasn't allowed.

Very hard to find correct Parts for vehicle even using vehicle selector- Ordered incorrect brake pads - correct rotors on first order. It took 2 phone calls to get a return shipping label and 3 emails. I also wanted to mention that when calling to order the new parts the sales guy, didnt get the name, was short and seemed very disinterested in my buisiness so I hung up and decided to try the website again after referencing the parts off the EBC website. Lastly, There was a billing issue when I tried to order the correct front brake pads, as well as matching rear rotors and pads that no one seemed to be able to give me info on. I had canceled the order through Amazon (my billing method) and thought Id try AGAIN to order my brakes. Maybe i'll have some luck this time otherwise the suspension, exhaust, intake and wheels I plan on buying from you will go to some competitor.

Easy and quick

It was nice and easy.
