Probably because the majority of people who bought the 4Runner (excluding this forum community) were considering between a minivan and the 4Runner when they bought it in the first place.
Most people don't use their rides as they were intended by design. My neighborhood is full of middle-aged bro-culture men who own full-size pickup trucks and do nothing with them other than commute to their desk jobs or go to the grocery store...and literally every Jeep Wrangler is owned by a teenage girl who has a row of ducks on the dash.
Bring back the RWD Station Wagon! Handles/rides like a car, has the interior utility (almost) of an SUV, and even typically looks better.
