Lots of everything 
- Fun, full on local contrast (and decompression in tone eq, top left → bottom right), lots of grain, orange-teal coloring galore, lots ot vignette (using exposure module) …
The Fiat is taking off… Many problems here:
As a rule, the chances that you can transplant a random picture into another random picture are very small, and many examples you see on the web use very carefully selected images or even images taken for that purpose.
A counter example is bunch of group pictures I took recently. No picture where everyone was looking at the camera with an acceptable smile, but since all the pictures where taken in a few minutes, lighting and perspective was the same on all and it was very easy transplant heads to make a group picture with everyone looking good.
The author of this post attached two versions of the photos, which I took as a bit of a joke.
It’s not all fo pa in this tongue-in-cheek montage.
In the Cuban landscape on the road incorrectly parked Fiat (they are not there )
Intentional incorrect scaling
No windows in the car
I’m a bit picky here…that is a Fiat 600 not a 500.
non c est une fiat 500 la 600 a le cul plus arrondie
It’s a Fiat 600D. You can google other Fiat600 and Fiat500 to see the difference (look at the moldings near the license plate or on the doors). Usually the D version has the doors with upwind opening. This one has a different logo, though. Maybe the restoration is not perfect, but it is a 600. Also look at the hood design.
bonjour tu as raison c est une 600 pas une 500
si tu sais me dire comment on obtient le développement du tracteur
c etait ma question
merci
comment faire
pour
Not sure what we are trying to do here. I mean, both are vehicles, but the pictures don’t have much in common. Especially the Fiat has no meaningful surrounding like the tractor has. There is not so much you can do, IMHO.
Anyways, here is a second try:
I did see in the original picture the following edit and tried to apply something similar to the picture of the op.
Additionally I did some sloppy masking, cropping, retouching and fiddeling with the tonal range.
Maybe this helps (probably not…).
Have a nice one!
The tractor image looks like an HDR to me, so created with multiple exposures and I can’t replicate it with one image and darktable. Here my attempt to develop the image.

Liberal use of local contrast for that HDR effect, shadows+highlights to reduce the dynamic range. Color toning from a LUT HaldCLUT Set: ANUBIS because I’m lazy to do the teal shift manually
