A Friends Control Number gets you 1% under dealers invoice (dealers invoice is in theory dealer cost).
Any rebates or incentives that they have available also apply.
The game dealers were playing for a while was that they would only take the Friends Control Number on ordered vehicles (BS pandemic rules due to low inventory).
I can fix you up with a Friends Control Number if it will help you, I get 6 every year (only used one so far this year).
If you're interested, message me and I'll let you know what info I need to fill out the online form to register you and get a number.
