Sorry, that's my bad habit :P I'd say that fry is rather easy. Scene setup is much easier than Vray or Mental. Material Editor is intuitive but you have to make few materials to understand how it works. Lighting workflow is different. There is only geometry light, no directional, spots, IES, etc. Just geometry and light emitting material. Nothing hard to learn though. Basically you do everything to stick with real world objects, materials...
Those Scirocco renders are just beautiful, especially the top side. Tolas, after seeing your 1st render I couldn't resist and although my knowledge is rather limited I gave it a try on the XFR with two skins I've made for it a while ago.
The lighting of the interior is too intense and the other lights need some more work, but it doesn't look bad so far I think.
Almost real would be then if the car is a little bit bigger and the reflections on the glass should be yellowish-orange or so And background should be lot better (quality), it has some noise and edges are not clean.
But for that Brazil is too poor. You must read tutorials and learn quite much.
It's quite noisy. If it's not on purpose, it could be due to a rather big compression factor when saving it as a jpeg file.
On another note, I've finished the side views of the XFRs (for the interior lighting problem of the top views, Tolas, I decided to deal with it by decreasing the window's transparency, but I forgot to MeshSmooth the wheels)
Actually there is floor on side and top views. It's pure black and the car is placed at the edge. Some of tyres are pimped in photoshop just to give more contrast and bring up highlights
