How does this sound?
1. Come in on the 13th and order a new Camaro
2. Leave a non-refundable deposit of $1000 (goes toward the purchase)
3. Let us keep the car when it arrives for 7 days on the showroom floor
4. We will sell it for just $1000 over invoice
This will save you money as it is way below MSRP and we will be able to generate some excitement at the dealership.
Lost me at non-refundable, so they expect you to purchase a car regardless of how much it is (you don't know yet) AND without having test drove/inspected it.
Its not like they wouldn't be able to sell it to someone else anyway.
Go somewhere else.
