Regardless, I see that you are not an amateur when it comes to buying VW products.
A few years ago, I went into a VW dealer with the intent on purchasing an Eos. I happen to see a brand new CC on the lot and after being offered the car at such a fantastic deal, I drove off with it a couple of hours later.
But.....I still wanted an Eos. A few weeks later, I approached my sales rep and told him that I would consider another new car if the deal was right. He knew it would have to be an Eos.
I told him, to the penny, just exactly what I was willing to spend and what I absolutely had to have in the vehicle.
It took a few days, but eventually the Sales Manager agreed to sell me the right Eos at the right price.
Stick to your guns. It's okay to want an Eos but not to the extent that you are willing to lose your self respect over. I, too, was only a few hundred dollars within making a deal, but held my ground.
Was it worth it? You betcha. VW products have a large markup and the Eos is not one of the best sellers in their line.
Wait it out, IMHO.
