I recommend keeping them. I sold my 16" OEM wheels from my 98 E430 and had to buy another set of rims and tires (used) for better trade-in value 3 years later. I had some 17" aftermarket rims and every dealer, even used car dealers would not take the car, insisted on the OEM rims or either marked the trade value down. At trade-in dealers do not want a car with any aftermarket parts especially ones they can not replace. They can easily replace an OEM rim but many aftermarket rims are discontiued and no longer available to replace a bent or faded wheel, etc.
