I finally decided to get my front bumper repaired. Thanks to other repliers on this thread I had an idea of what was reasonable and how the repair might be done.
I also had a right front wheel curb abrasion repaired as well.
The bumper work involved bumper removal (as well as clear bra removal in that area) and the repair itself used either a nylon or kevlar material to reinforce.
The wheel repair involved filing to smoothen, then rebuild with metal, and then finally a clear coat to finish.
The total job was about $560.
I also had a complete interior and exterior detail job (normally $225) done for $89, thanks to Groupon, which is how I found them.
The name of this company is called BumperDoc (in Escondido, CA). They have multiple locations and are expanding to other cities.
They also provide special discounts for firefighters, police, seniors (60+) and Porsche Club of America members. I asked if he (francise owner's name is Ron) would provide the same discount to SLK forum members and he said he would.
Before and after pictures are provided.
I was grinning ear to ear when it was all done!
