If you are going to make an offer start at 40 percent off msrp, you won"'t get it but it is a starting price. Be sure that the msrp is a true figure by looking at several dealer sites and remember you can always go up on price but you can never go down once you make the initial offer. If you have a trade it's meaningless. Your only concern is the difference. Try to sell your trade on your own, price it below competition and it will sell.
