700 miles are extreme.
I have taken delivery of a new car before, a luxury car actually, with couple hundred miles on it because I wanted to car and asked them to get it ASAP. The dealer sent a couple of guys to drive the car back from nearby city.
However, even if the car hasn't been titled before, I would consider it used at 700 miles. I don't want to add to your insecurities, but at that point I would have demanded to knock off $3000 or so. The dealer would have never sold the car "as new" with 700 miles on it.
