Welcome to QUALITY OEM INC, a fast-growing family-owned business located in South Florida. We are glad to offer you a wide range of used parts for. AUDI, BMW, MERCEDES, JAGUAR, LAND ROVER, and PORSCHE. In most cases used electronic auto parts need to be adapted by an official vehicle dealer or certified mechanical shop, i. Reprogramming or removing of anti-theft protection from your vehicle might be required. So, if you just plug an item in, in most cases it will not work or will not work correctly. Though, whenever possible, we will do our best to dispatch your order the same day. International buyers will often have to pay import charges. If the item is not what you expected or you think that it might not work, please choose “DOESN’T FIT” as a return reason. We do not compensate installation costs for any reason. Our reputation is very important for us.
