This isn't great news if you are thinking about buying a new luxury SUV and planning on keeping it for only a few years. However, if you are in the market for a used luxury SUV at a good price, waiting five years for a model to drop in price is a shrewd move. The X7 is not the only one either, because this is a pattern that has long emerged in the luxury market; some excellent used luxury SUVs out there have depreciated into bargains. The good news for used luxury buyers is that the QX80 is the luxury SUV with one of the highest depreciation rates. Combined with good sound deadening, smooth ride quality, and all the space on offer, it still delivers a proper luxury SUV experience, despite its aging tech.
