Low res models
      

  Blunt answer incoming, only because this has been addressed a whole lot.There's no reason to pump up poly counts and texture res for a model you're going to see from a fixed camera 30 feet up in the sky. At that distance the detail is lost, and so essentially we'd be building a model so it looks pretty on the website.Which might actually be cool ..
