Blimey, that looks photoshoped ! (I'm guessing it isn't?)
ther is an element of PD but its using layers, you use the flash to light the car up, so take 4/5 photos with the flash in differnt positions so it lights the car up, layer it in ps and bang you have a spanking photo like that!! obviously not that simple but with the one i bought it has lots of settigns so can reduce the power of the flash etc to get the right lighting,
ill post up some attempts once it comes thorugh
