I have the 2002 75th anniversary edition S40, US specs, and it was not available with the color matched body moldings. Only things it came with that are different from a normal was floor mats with the 75th logo on them. The "anniversary edition" was just priced different, adding in the Premium plus package at a lower price.
I know that the new 2003's are available with this and the T5/XC70 style front grilles. Maybe it was just a new 2K3 you saw.
