I did the LF fender on my '95 E300D recently. Fairly straightforward. The bolts you have to get to thru the door opening can be a bit tricky to get to, as are one or two which bolt to the front bumper molding, but it's a half-day Saturday type job.

I don't know if your car has the plastic molding "cladding" panels on the lower part of the fender, but if so, plan on buying some new plastic clips for those, as you will probably break them when you pry the cladding off. The clips are cheap, so just get a few. FYI, I bought an aftermarket fender from Adsit for $99. Already primered. It fit just fine, but I could see that it wasn't quite as precisely made, and the gauge was very slightly thinner than the OEM. In my case, my car is a commuter special, i.e. don't-worry-about-it-in-the-airport-parking-lot mobile, so I'm not hung up on originality, etc.

Had it undercoated and painted at the body shop for $150. Looks absolutely fine.
