I bought an aftermarket left fender for my 190D. It was mostly perfect, but the rear edge didn't match the form of the door. The error exceeded the range of all available adjustments. The only way it could have worked would have been with a cut & shut by a good torch guy. When I called the vendor, they told me that I should bring it to a body shop. Instead of throwing good money after bad, I bought a good used fender, which dropped right into place without much fuss. Instead of a replacement fender, get a real mercedes fender.
