I have to agree with Smuttysy. Only few standards were upgraded, like that infamous kei car.
It's great to see new shaders, wheels and basicv interiors in standards now. I think PD won't make anything more with them, but there is one thing that would be awesome. I hope PD will now focus on making new premiums, but they could outsource texture upscaling of standards. It's major thing that makes standards look bad. Look at Accord Euro-R. It looks great, but also it have little amount of textures. Now look at nPug 206WRC, or Audi Rs4, they are really bad.
I made a little experiment, how standards could look with upgraded textures (ONLY textures, no 3d model smoothing).
Result is below (make sure to see it in full size, sorry for huge pic). And don't say it is so easy. Upscaling texture is one thing. Another one is making totally new UVmap (it says game whete to put texture on 3d model), but despite that I think it's doable even by guys like me, who just want to help save standards
