It's not uncommon. Did the dealership you bought from have the car you wanted on the lot, or were they trading with another dealership to get the particular color/package you wanted? When we bought ours, that's what happened (and what we knew would happen since we knew where the only one was, but wanted to buy from our local dealer). They drove the car up from the first dealership, which was ~75 miles away. That plus test drives put it around 200 miles off the lot. (And they drove one of their cars down to trade, so presumably that car went off to its new home with a similar number of miles on it.)
