What's really going to make the price drop is the consumer discovering the older versions (especially the MK III). Mechanically, the MK III is almost identical, it just doesn't stand out as much visually as the MK IV.

The MK II has grown on me as far as appearence, and for a Supra customer that wants handling over power, it's the way to go.

As far as the Celica Supra, well, that's just flat-out old school and already rare as it is.
