Well, if you're going to separate out fun cars and practical cars, I think it would be cool to have a fun activity superstore for adults where you got to do fun things that you cannot afford to make a part of your daily life. Things like driving an Aston Martin around the activity superstore parking lot, or having a section of the activity superstore that is dedicated to spa and salon style activities (whirlpools, saunas, massages, meditation, yoga, hair and nail stylists, etc.). Perhaps the activity superstore could have a section with the latest in technology that you could play with, like the latest gaming, tv and movies, computer technology, cameras, etc.
The activity superstore could also have things for sale or for rent as well (an interesting concept, renting technology or cool stuff like a motorcycle or Aston Martin, but just for a week or weekend). It could be nearly like a grown-ups theme park, but instead of pretending you are a child, in the activity superstore you can pretend that you are in an Aston Martin, pretend that you are a professional photographer using the latest 3D camera technology from Japan.
While some might say that this is pandering to the materialistic culture of today, allowing people to pretend that they are rich without actually having to work for their own wealth, and while they do have some point, there could be a place for an activity superstore like this. Perhaps this would help keep some people from feeling like they have to spend their whole life working to get this things. Perhaps some people would be encouraged by it. But really, it doesn't matter what you do, activity superstore or not, people will still be as they are.
