986 prices are going up?!

[Duster]

Check out the Sept. 2006 issue of Excellence, specifically the market update on the 986 (Base). It seems that MY 2000 pricing has gone up for 2006.

Low pricing for 2005: $15021
Low pricing for 2006: $16326

High pricing for 2005: $22863
High pricing for 2006: $24850

I wonder why only the MY 2000 prices have gone up and all the other MYs including the "S" have stayed down?
