Consumer Demand Index for Performance Products and Accessories (CDI) – May 2013
About this product:
The SEMA Consumer Demand Index for Performance Products and Accessories (CDI) measures purchase intentions of consumers (both enthusiast and mainstream) over the next 90 days. As enthusiasts represent approximately 10-15% of U.S. drivers, the Index is 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 2013 report is based on 825 interviews conducted nationwide via Random Digital Dial (RDD) telephone survey. Since last month, the index decreased from 50 to 34.
