In reality, this has been a good year for new car sales. Incentives and low interest rates combine to stimulate that, along with people that held onto their aging car due to the bad economy these past few years.
That said, any vehicle you buy, regardless of what it is, depreciates most early on and then levels out. Unless you have something desirable that everyone wants and nobody can get their hands on, it is to be expected to take a hit on a fairly new car. After all, if you were going into a dealership and the price on the "newer" used car was close to the price of the new one, not to mention better interest rates on the new, which would you buy? That's just the way it is. How will it hold its value when it is 5 to 7 years is yet to be seen, but I don't have any illusions, since the Impreza, in and of itself, is nothing special. Having said that, mine has worked out well and I am happy with my decision to have gotten it.
