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 July 2011 report is based on 905 interviews conducted nationwide
via Random Digital Dial (RDD) telephone survey. The overall index
experienced a decrease from 38 to 28.
