Premium - gallery view available
Updated standard - gallery view unavailable, interior possibly darkened, but otherwise premium. Good "tells" are highly visible polygonation (well-updated standards won't have it) and whether the panel gaps are part of the mesh or just textured on (looking at them under a bright reflection might help but this isn't alwasy 100% reliable - note that textured-on panel gaps are often wider, darker, and more jagged than 3D panel gaps). Note that the quality of the updating seems to vary a lot - the AE86's seem to have had a bit of work done to them, but the Levin's headlights and the Trueno S.S.'s wheels still look standard. Lastly, you can just sort of tell by the look of them - standards will have a sort of "one-piece" look to them, and may have a brighter, almost chintzy-looking sheen to them.
