How many unoccupied vehicles are involved in accidents, they are news items often,."owner crushed" "child killed".
If this is a problem with your undelivered car, Don't accept it. If you already have the vehicle, contact the dealer and tell him to collect the vehicle and fix it. All quite simple.
I would not accept this crap from any dealer. Wake up MMC and get your act together.
I would go public in a very big way.
