A_Cro Thats a stacked image (which i presume is why the exif info cant be seen)... my one long exposure i put onto flickr and also into photog chat & questions as it had a strange mark on it, also, i didnt like it much!
The focus may well be out, i tried auto focusing it... but as it was low light it wouldnt do it itself... so i tried manual focus, and tbh didnt spend enough time trying to get it right, as i found it very difficult!
I'm currently stacking another set, but all of these have kinda been experiments, so that when i find a good location, and have a clean car, i can do them in confidence that i'm not wasting my time!
next experiment will be light painting/ stacking of a picture of the car to see how that works.
