For now, let's work with what we know from HybridCars: by putting flyers on Prius windshields, TSG found that all Prius owners were "very happy" (88 percent) or "somewhat happy" (12 percent) with their cars. They're also mostly well-to-do (71 percent earn more than $100,000 a year), male (58 percent) and over 40 (73 percent). But, the headline that hybrids (or at least the Prius) pay for themselves, is only hinted at with the line, " Most of the respondents used longer periods of ownership and higher gas prices than usually used by journalists. As a result, the shoppers found hybrids to be a compelling financial transaction."
We'll see if TSG puts their release online and then return to analyze it a bit.
