Being local to Gary Lang, and having a few friends that have/still work there, they are only trying to get your money. I was originally going to buy a wrx from them, but they wouldnt budge on their prices. I drove an hour east to Highland Park and spent 4k less for a lower mileage car (same year, an options). Like hoffmanestates said, it wouldnt hurt to change it. Its really your call whether you want to go ahead and have them change it. I think you would be fine sticking to your regular schedule.
