Run away from your friend’s friend. They are not doing you any favors. I would strongly recommend you do some reading: Leasing 101 — EDITORIAL | LEASEHACKR.
If the dealer was honest, they would have laid out all the details for you.
If you did a search for penfed, you would have come across this thread: PenFed Benefits - Up to $2000 AUDI MB FCA JEEP (usually $500 towards leases).
Good luck in your search.
