Consumer Demand Index for Performance Products and Accessories (CDI) - May 2011
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 May 2011 report is based on 900 interviews conducted nationwide via Random Digital Dial (RDD) telephone survey. The overall index experienced an increase of 27%, from 22 to 28.
