"VW made vehicles that were stated as X emissions compliant, and no consumer actually knew, nor probably cared ..."

Most consumers couldn't care less whether or not their vehicles were emission compliant. However, most REALLY care what their fuel costs are. The cars are illegal to drive or sell as is, and retrofitting the cars substantially reduces their fuel economy.
