About this product:
The SEMA Consumer Demand Index for Performance Products and Accessories
(formerly PADI) measures purchase intentions of consumers (both
enthusiast and mainstream) over the following 90 days. As enthusiasts
represent approximately 10-15% of U.S. drivers, the Index is likely to
be an indicator of mainstream consumer demand for automotive specialty
and performance products.
The Consumer Demand Index is a
weighted composite index, set to an initial value of 100 based on
demand levels benchmarked between January and March 2007.
The January 2010 report is based on 923 interviews conducted nationwide
via Random Digital Dial (RDD) telephone survey. The overall index
experienced a seven point decrease from December 2009, dropping from 38 to 31.
