Actually that means they didnt go back and rescan all those 800+ cars, retake all those photos. They just used the info they gathered on them over the years and just built them for GT5. So those cars will have slightly less shine to them that makes them not premium. Premium cars are cars that were scanned and photographed in recently. Meaning they have high quality up to date information, and these cars were built from the ground up to deform in ways the others weren't built up to. Im pretty sure that Kaz and the crew took photos of the cars inside and out during all those years of making the other GT's, it wouldn't make any sense if they didn't. GTHD cars sported interiors, so I don't understand why even those pretty much GT4 HQ models had interiors and GT5 LQ ones won't. They'll probably be run of the mill looking, standard viper interior(gauges, lighting, wheel, shifter, plastic trimming), premium viper(everything but the plastic, high fidelity looking leather upholstery, fully working gauge cluster, visible stitching on leather, etc.)
