I'm overdue, but I wanted to thank this site and the organizers of the DC-metro group buy! I worked with Nader and drove down from NYC to purchase a 2014 JGC Overland about six weeks ago. He was honest and easy to deal with.
I did have classic "dealership complications" with a trade-in and a warranty purchase with the financing department, so be aware if your business involves those steps but you can trust that what Nader tells you is what will happen, which is an incredible relief when doing business at a dealership.
Also, as others mentioned, the other NYC-based dealers I'd browsed with were CERTAIN that Nader's estimate was a bait-and-switch: "impossible! You're going to end up with a Limited..." I don't think so. Thanks again group! I look forward to continuing to learn from everyone here.
