I like the car in the image ... I also really like the composition of the elements. My only critique is that, personally, I like to see a lot more contrast in black and white shots - this is a little too bright for my liking (making the image a little washed out). I also like all the lines and angles - really works well.

I agree - it is a little washed out. Maybe you could amp the constrast up a little more in Photoshop. Other than that the composition is nice - good lines and perspective. I agree that the car improves the image - it is nicely framed by the underpass.
You could clone the car out easy enough. I agree it is a little bright - assuming the original shot was colour there is more than one way to desaturate a photo, so it may be worth playing with. I like the composition of this image.
