I paid $440 about 18 months ago but these dealer parts are going up like crazy. Did you try Park Place in Dallas (214-526-8701, wholesale to MB Club members from 1st to 10th of month) or Caliber Motors (800-252-6877, again ask for MB Club discount, or just beg for a low price)? SSF has them but not cheap - it's pretty much a dealer only part.
