Here's one data point to support what others are saying. I recently purchased a 3.3T G70 (Arizona). I spoke with at least 20 dealers across the country before buying. (As an aside, the customer service was generally horrible.) As soon as I mentioned wanting a discount off MSRP, most dealers stopped returning my phone calls and answering my emails. I ultimately ended up getting back in touch with a couple and they flat out told me that their owners/managers wouldn't entertain any discount so contacting me was a waste of their time. The salespeople were pushing their GMs to discount, but they wouldn't budge. I finally got a couple dealers out east to offer a discount in the $1500 range, but those were AWD (I wanted RWD) and/or the cost of shipping basically nullified the discount. The AZ dealers wouldn't discount at all.
I'm a business school professor. One of the things I teach is negotiations. At then end of the day, negotiating power generally comes down to who has a better alternative to a negotiated agreement. The dealer's alternative is to wait and sell to someone else. Your alternative is to go somewhere else, buy a different car, or not to buy a car at all. Given how new the car is out here in AZ, the dealers were happy to wait for the next customer. I am not a pushover when it comes to negotiations. I generally get smoking-good deals on cars. With the G70, I walked away from 3 dealers and they couldn't have cared less. They are utterly convinced that they have the golden ticket. If you can wait a few months, you are likely to see more discounts. As supply increases, customers have more options. Your alternatives get better and the dealer's alternatives get worse. My lease was up so I couldn't wait without it being a massive hassle. I also wanted a very specific trim/color combo and there was only one of those G70s in the entire country. (Before you ask, no, I didn't tell them that I only wanted that combo.) I had to negotiate pretty hard just to get it at MSRP with no dealer add ons. If you're out east in places that have more dealers in the area (e.g., NJ, GA, VA), dealers know that customers have options. They should be more willing to deal. Just don't expect a massive discount like you might see on an Audi or BMW. I will add that several dealers offered to discount the 2.0, but wouldn't move on the 3.3 price.
