We have most US model Mercedes in our year and model search. If you have a European model/grey market model or another model you cannot find, you can email us at or call us at 800-521-7656 and provide your year, model, and VIN# along with any parts you are looking for and we will be able to assist you.

With the vast number of products in our inventory and the ability to special order parts, not everything is on our website yet. If you cannot find the part you are looking for, you can always send an email to or call 800-521-7656 and we will help you find the part you need.

A core charge is a refundable deposit made on rebuilt parts (some new and used parts, too) that is used to encourage buyers to send the old unit they are replacing back to us. Once we receive your old part back, we refund the core deposit amount. The core charge amount is listed in the description for any item that requires one and is included in the final price you see for that product. For more information about cores, see our Core Returns page.

Yes! All new and rebuilt parts are covered by a 1-year replacement warranty and all used parts come with a 90-day replacement warranty. A 2-year extended replacement warranty is available when purchasing a rebuilt transmission along with a rebuilt torque converter.

It is very difficult, if not impossible, to diagnose a mechanical problem over the phone or via email. We try to avoid guesswork when recommending parts: we don’t want to send you the wrong part just as you don’t want to receive the wrong part. If you need help diagnosing a problem, you should try to find a local mechanic that knows how to work on Mercedes vehicles. Once you know what parts you need, we will be more than happy to help you!

Damages during shipping sometimes occur and we want to make the process of sending you a replacement part as easy and fast as possible. If a part you ordered arrives damaged, you will need to take pictures of the damaged part and email them to us as soon as possible so we can initiate a damage claim with the carrier. You must provide the following photos in order for the damage claim to be accepted:

● A photo of the damaged item
● A photo showing the damaged item inside the original box with all of the original packing
● A photo of the packing material used inside the box
● A close-up photo of the shipping label with the tracking number visible
● A close-up photo of the box manufacturer’s certificate, if available.
● Two photos displaying all six sides of the package
● A photo of the box’s dimensions, usually printed on one of the bottom flaps of the box.

For more information about submitting these photos to us, please see our Returns Policy

If a replacement item is available, we will send it out as soon as we receive notification from you that an item was damaged in shipping. If no replacement is available, we will issue a refund for the item.

Please keep a hold of the damaged item and the packaging it came in. The carrier may come to pick it up or inspect it as part of the damage investigation. We may also ask for the part to be sent back to us.

There are many different models and body styles for Mercedes, so ordering the wrong part can sometimes occur. If you ordered a wrong part by mistake, and you have an account with us, you can initiate an RMA (Return Merchandise Authorization) request. Once the RMA is reviewed and approved, you can ship the incorrect part back to us. We ask that buyers pay for return shipping on parts ordered by mistake.

Once we receive the part back, we will work with you to find the correct part to send as a replacement.
