With the rebates and everything, you should expect to pay at least $1500 below invoice. If you friend has a business, let the dealer know and they will toss in an additional 300. 00 discount. Unless he is a member of Farm Bureau, that is an additional $500. 00 but cannot be used with the business deduction.
Squeez'em tight. Check online at some websites. Consumer Reports has a service that would give you list prices. I take into consideration a 10% mark up plus 3% dealer hold back. So there is about 13% to work with, plus rebates and incentives.
