For some time I’ve been playing with Maclaren P1 model from forza game.
Here are some renders I did recently. Rendered with cycles on GTX 780. Around 10-15 minutes per image.
This is epic! You nailed it! I would certainly take this as an official poster in the right context! 5* 
That last one is amazing! You sir deserve a cookie for your amazing composition/rendering skills.
That is very realistic looking! Kudos to you man!
Really well done!
Awesome! I love the setup in the last image.
Awesome! I’m so impressed by the last image from the first thread. Can you help me to have your nodes and environment settings sharing them? Please, I like this compositing. Very good done. Congrates.
This one looks so realistic! congratz bro
Thanks again guys 
Here is a car paint node tree. It’s pretty simple and straightforward 
The background environment is a free hdri map from hdr-sets.com store:

The node setup is pretty simple. I’ve used separate maps for reflections and for lighting to speedup the rendering a bit:
The composition was done in photoshop so there is no any node setup to share.
I’ve saved the render in 32-bit exr format. Two separate files – one for the floor and one for the car.
In photoshop I always use camera raw built-in plugin to bring the details to the render using the basic shadow, highlights, black and clarity sliders. The background is a photo from pixabay.com which is blurred with “field blur” photoshop built-in plugin.
Thanks a lot Beep for the sharing.
Nice angle!
These are some very nice renders you are posting, keep em coming! I like 'em a lot!
Really impressive! You’re an inspiration for our car modelers!
