4. Service and maintanance.
If you don't get foot marks on carpet means it's not serviced. That's trademark of m&m
If you still have one complain left after delivery from service center than they have addressed other issues
If it's not washed after service than your attendee has half day off.
If it's delivered late in the evening than some one is trying to cover up something
If your bill is not above 25k after 4 years of ownership than either you have not driven the car or service center is related to you......
