That "kid" was a GTPlanet moderator.
And regarding your question;
It was confirmed not so long ago that there will be two typed of cars, standard vs premium. The standards will have no interior/cockipit, low beams, less damage effect and are basically just upscaled models from GT4. Whereas, the premium models are beautifully modeled, HAVE interiors/cockipts, high beams and more damage effects.
Which is why this thread was created. For people to give their views on what they think about standards and premiums. IMO, its prefectly fine and I'm happy with it.
