Great commercial. It actually has a deep meaning.
This is what I got from it.
The dad was a hard worker but little time for the family. So when he is not there it is business as usual, but he is actually getting his son a welcome home/congratulations and I'm sorry all in one.
Just because he wasn't around much didn't mean he didn't care for his son/family.
Shows the power of a mustang to say all that without a word spoken.
Drink that in.
