"W" is the short wheelbase and "V" is the long wheelbase.......brand new I think the long wheelbase was about 3K .I think it had some standard features that the short did not,,,,such as headlight washers.........seems that most people opted for the long wheelbase version in the S320.....so I would imagine the long wheelbase should be more expensive as a used car
