stuff from the first Forza like the S15 Silvia and F355 have been using the same models just upres'd since the original Xbox. They were modelled off photographs because the devs couldn't get access to the real cars, which is why they're inaccurate.
anything they've added since about Forza 4 in 2009 has been laser-scanned, and anything from Forza 5 on the launch Xbone is so detailed they still can't use the full 1:1 scan in actual gameplay because it'd have too many polygons (the full laser scan is only used for static display in the menu)
