Well I had the same problem when I bought a new bumper for my 300E. I days later, I bumped another car, It dented my pumper and the impact strip was TKO'd, I went to the parts shop and they told me that the impact strip can be taken off the bumper and replaced. I did that, its easy, just take off the bumper(4 bolts!!!) and take the strip off from behind the bumper.
Hey if you plan on getting a body kit PM me and see if we can get a discount on 2 bodykits(Iwant one!!).
Buy the strip from FastLane(Look at the banner on top of the page).
I'd get a body kit though,any excuse is still an excuse
