My brother receives this on several makes of vehicles, including 'The Big Three'. (lucky ba@tard)
I've only gone with him once a few years back when he was ordering a vehicle. One VERY important thing...
DO NOT let the salesperson know you have that at the time you are negotiating.
Wait until you get the best possible deal, and then let them know you have this discount.
In my brothers case, I believe they issue him a certificate which he presents at the dealership.
It may not apply to all models either, re; Corvette, new Camaro...not sure.
