Hi Eleonora, Good shot, the angle shows the split bend in the wheels perfectly, and creates a very interesting scene.
As to adding an old air to an image, I feel a bit more ambiguous, both to adding that air, as well as how you did it in this photo.
First, I think adding a dated look to a photo is widely overrated, as it imposes an atmosphere, which wasn't there in the first place. Apart from artistic freedom, in which it can serve a purpose, I believe in most cases it distracts from the photographical merit of the photo, in stead of adding to it. To me, such Photoshop manipulations do not improve a photo, but create a redundancy and distraction. This is, of course a subjective opinion, and I know many people like it. It all depends on how far you're willing to take it. Adding tears, scratches and stains would create a vintage feel to any photo, but would create digigraphy....:)
In this case, I can see the point of converting it to B&W, which would already create a timeless atmosphere without creating a redundancy or being distracting.
You could also try the colour mixer in photoshop, tweaking the original by changing the green, blue and red hues to a more yellow tone. Desaturating a few levels using the hue / saturation could also work.
In this image, I think you're already half way there, and I would only consider reducing the saturation of the green levels, maybe changing the hue a bit, as well as playing around with the contrast and brightness a bit.
