Firstly the shot at the bottom was probably extensively worked over to enhance just about everything.
It was also taken under totally controlled conditions with a professional lighting set up and could have been made from a montage of several shots (note how the lighting on the bonnet and windscreen does not seem to relect the overall lighting set up.)
Add a polarizing filter and you are probably there.
Your shots were taken in surroundings virtually guaranteed to make them look lifeless.
Try shooting outdoors, setting the White balance on your camera and with a polarizing filter.
The add some colour later when you have got everything else right.
And get low down and closer in.
