The shot is illy composed. there's a lot of weight to the right of the frame for no reason. I personally don't like seeing cars cropped, at all, unless there's a reason--like a detail shot.
the reflection of the greenery is distracting, not a compliment. You want to highlight smooth/clean lines, the reflection is distracting and doesn't show off the extended fender of the GTI. It's also casting a yellow/green hue on only half the car.
The hood is completely washed out from the direct sunlight.
The horizon line needs to be leveled off; the car appears leaning in the frame.
Car photography is very tough. You have a boring object that you need to make look good. you have to think of all the reflections, and all the light challenges, as well as creating an interesting frame/composition.
Like here's a really cool car:
Car Wallpapers - Part 58
But with maybe the exception of one, none of these images do anything for me. So even the coolest of cars need help.
Compare these two shots:

and

Same car--
very similar shots--but one is MUCH more successful than the other.
The one that is more successful used a longer focal length, so the background is compressed and narrow, and the car looks more attractive and less bloated.
It was shot lower down so the horizon line is visible.
It's using a short DOF so the car pops out against the BG.
There's no distracting lighting/reflections on either, in fact the lighting is VERY similar, but the better image took more care in smoothing/evening out the panels and putting emphasis on the highlights (look at the hood and headlights).
Both have fairly plain scenes they are in, both one makes more sense: it's sitting on a track. The other is sitting in what looks like a park; boring.
The better shot also put the image through post and richened the blacks, and added a color cast that gave it a good feel.
There's a big difference between these two similar shots. One screams snapshot, like yours. The other screams: Hey, I put some thought behind this. The first thing I thought of when I saw your shot was that you were trying to sell the tow hook on a forum, because you realized a street car doesn't need to be pulled out of a sandtrap very often...
