Cheers chaps.

The way I did this one was:

Fists process the raw and drop into Photoshop, get the the levels, contrast, brightness right in the original, then balance the shadows and highlights. Then make a copy.

With the copy, using the Polygonal Lasso go round the edge of the car, expanded up so you can get in nice and tight. Once you have gone all round, select inverse, then select refine edge, feathering out just past the edge with a nice smooth contrast. I then hit the delete button, leaving you a mask layer of the car with a nice smoothed edge.

You then select and convert the original copy to Black & White in Silver FX Pro. Choosing something nice and moody and contrasty. You then open up the car level over the top, select the eraser, nice and small with smooth edge, then erase gently round the edge of the car, to remove the feathered edge.

Once that's done, flatten the image, make a final levels adjustment, dodge and burn as required and then add the vignette. Final flatten and job done.

About half an hour to do it properly
