I'd go have a look at it before okee dokeeing the repair. Are the arms dented but not bent? I'd probly live with it. Front arm is solid forged so if its bent that is a pretty good sign of a big hit. If the rear control arm is dented being pressed sheet metal it could be dented but not bent out of shape. (240D right?).
