I use corel XI, and used most of the functions PS seems not to have, but i'll give you a rough idea of what i did.
1.Took the original image, and made a -2 and +2 exposure, and compiled an HDR using photomatrix.
2.Mess around in tone mapping, and with light smoothing on pretty high.
3.Opened the HDR in corel XI, used the selection tool on circle mode, with a feather of 200, and circled the car, inverted the selection so everything outside the car was selected and lowered the levels to create a subtle fake vignetting.
4. I then used the clarify tool (LOVE THIS), which is similar to the effect that HDR makes. It emphasizes shadows, bringing out detail which you can see in the windows.
5. Then did a high pass sharpening, not entirely sure what this does, i know it sharpens the photo, but i got a feeling it also adds more contrast to small shadows while not effecting anything else.
6. Used a warming filter to give it some colour.
7. Resized and added a border.
