Best Negotiation Tactics - HELP!




How does the loyalty discount work exactly??
I'm thinking of ordering a 2013 ML350 3 months ahead of my early lease return date for my E350 and I also wanted to know how many of you have had experience with the Costco Auto buying program.
Is it possible to combine invoice pricing (given by Costco) with the loyalty discount? Should I even mention that I own a benz in negotiations?
This is my first time ordering a car. Last question: Should I do negotiations before the car is ordered with the dealer or after it has arrived?
Thanks for the help W166'ers
Dealers would rather sell you a car on their lot, but they are happy taking orders too. They'll WANT that order and you will have leverage and negotiating ability until you actually place it/sign it.
From reading posts on this forum, I'd say it should be reasonable to get a minimum of a 6% discount, and easily more, if you have a USAA or similar membership like Conquest, Costco, or whatever. Some have claimed as much as 10% WITHOUT any memberships. I just bought a new ML and got about 10% off with USAA. I was reasonably happy with it even though I could have probably done better.
First search a dealer that has your car in their inventory as the negotiation will be much more in that case. Unless you are ordering a very unique package or live in a remote area finding an exact car is not difficult. Negotiate before you sign your order or contract paper. Tell them you have loyalty rewards as dealer want your business as those rewards are cash money for them paid by MB and they might get you some more discount to sell the car.
I got 13% discount and I am not a USAA or have any loyalty discount. Went on the last hour on a last day of a month and picked a car out of the lot( they had my choice)
