What am I looking to pay for a brand-new Prius V if I pay cash what should my negotiating parameters be?

Paying cash doesn't give you any more negotiating power than financing on a new car. In fact, it often gives you less.

The best case scenario for the dealer is if you buy the car from them and they set-up the financing through one of their preferred lenders (bank or credit union). In this scenario, they get paid in full by your lender, they get a kickback from the lender for placing the business and they make money on the sale of the car.

If you pay cash, they can't get the kickback from the lender. While they will gladly accept your cash for the car, they would rather you finance. This means cash gives you no additional buying power.

If you want to know what a fair price is to pay and you aren't a 'car expert', use a site like truecar.com. Then go to Edmunds.com and see if there are any additional manufacturer to dealer incentives that truecar does not show. Between the 2 sites, you should get a good feel of what you should be paying (cash or financing).

don't know depends on the car sitting in the lot and how long its been sitting there along with what the options are. walk in and talk with a salesman if you don't like the final then walk out the door. most salesman/woman will probably stop you at least once and come back with another offer. now's the time if a new 14 is still sitting there
