I had a week to buy a hot new car with very popular options/color combo.
(Which wasn't available anywhere within 500 mile radius as I'd learn.)
So I drive to store X (small timers) where they tell me: Full MSRP, plus however long it may take to special order you desired trim.
I drive to store Y (small timers) where they tell me: Full MSRP, plus we'd prolly have to do a dealer swap with a store in PA.
So finally I drive to the biggest local dealership carrying that make.
The guys says, matter of fact we have what you're looking for coming in next Monday.
I said, GTFO !
He goes, I kid you not - then goes and grabs the book to show me what's on the next truck.
I damn near shat myself
So I said, could you shave 60% off the mark-up for this deal ? (The balls on me, eh ! )
I had the invoice @ hand and the checkbook was almost popping out of my shirt pocket.
He says, lemme talk to the Tower.
Then comes back and goes, we'd be willing to do 1/2 a mark-up on this car.
In the end not only have I saved myself a 2 month long clusterfick by the name of build-to-order, but kept 4-figures in my pocket
