I think the front on shot looks really good, the flash behind the car gives a great gel like effect on the garage door and you've got good highlights on the front of the car. My only comment would be when I saw them on flickr, the almost Paul smith style paint job on the grill looks like jpeg artefacts on medium size photo.
I'm not too keen on the side on shot, but that's because I personally don't like the rims, photo is technically good in terms of lighting, the slope on the approach to the garages creates a weird perspective though.
