So I have been lurking here for a while, and doing my research on my next replacement in the next few months (used M3, new C63, new RS5) and I am trying to coordinate the best method for negotiating a price. I will admit that I have been lazy in the past with purchasing cars, as I have never has to negotiate with the dealer (brother worked at one dealership and we paid the dealer price, Costco at $100 below invoice, auto broker on BMW, etc). Now for the C63 I have a few options and it seems that people are paying all over the place.

1. Costco if offering $200 above invoice for a C63, no (or difficult) negotiation fro anything more (cannot combine with AMA/USAA). Is this a good deal right now?
2. I belong to AMA and USAA, and the Fleet discount is $2500 off negotiated price. I assume that the Factory incentive above can be added, but are people able to negotiate close to invoice pricing to spring the $2500 coupon at the last minute?

If anyone has any advice on which options to add, I am all ears. It seems that once dealer is Costco, and will not negotiate any more, and another dealer does not do Costco, but will match the Costco price using the AMA discount. When I searched before, the deal for Costco was a few thousand above invoice, and the people were using USAA or AMA for E or GL class.

Yes, negotiate with the dealer on price then bring up the fleet discount. Salesman told me MBUSA gives the dealership that money so it's as good as cash to them. Not sure how the Costco thing works.

So if my math is correct, pricing this thing out is MSRP $90,600 and Invoice $84,500. I assume that you had some incentives, but to get it $6K below invoice is impressive regardless of the incentives. I could not even begin to come this close.
