Consumer Demand Index for Performance Products and Accessories (CDI) - October 2009
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 October 2009 report is based on 927 interviews conducted nationwide via Random Digital Dial (RDD) telephone survey. The overall index experienced a nine point decrease from September, dropping from 45 to 36.
