I'd rather have a dealer
not fix minor body damage before I see the car; then I know the full extent of the damage and can make sure it's repaired properly. If I discover a repaired area later, I'd always wonder how bad the damage really was and if the area was prepped properly before the repair - for example, not replacing a front turn signal that was smashed in transit by mounting the new one with rubber drywall anchors, which were totally invisible until I had to take the turn signal apart to replace a bulb!
