how much of a discount should i get? the sticker price is $14,100 but i want to know how much can i expect them to discount it for if i am paying cash for it. They might say nothing because it is brand new, but i want to know what i can expect or reasonable.

I don't think you will get any discount

cash is not an advantage... dealerships prefer credit as they get a commission from the creditor/finance company... my suggestion is simple try many dealerships and also to save money try and get a demo model

The dealership would prefer you finance. They get a % from the finance company, if you do. If the dealership you are looking into has a website and provides on-line quotes, check there. Usually they will provide you with a lower price. Dealers don't have much room to negotiate on new vehicles, used are a different story. I would look on-line and see if there are any eligible rebates on the Yaris as well.

No matter cash or credit. Do what I do, I never pay over invoice for a vehicle and that is before any incentives. Find the vehicle you want and tell them you will purchase it for invoice.
