Disintegration effect with particles on a car

Artwork Blender Tests

I 've watch a Vray demo reel and I was impressed by an disintegration effect. I try to achieve this. http://www.youtube.com/watch?v=hQCvvlfnPEg (at 1:40)

First we have a nice car (From Andrew Price at blenderguru.com thanks guy). I basically animate it and duplicate the car, resize it a little bit and change the color.
On the first car I make a particle system with a solidify modifier, an edge split modifier and an explode modifier. I use an empty with a force field to make the particles fly (sorry for my english)

So the video is an opengl view, I have a weak laptop and the rendertime is dramatically slow, so I hope you will download the blendfile and give me advice to improve the animation/simulation.

An other disintegration reintegration effects,
It’s from to sequences, the second has been “flipped”. I made an error on the direction of rotation of the second object(a radio), but it’s only a test, and I think I have understood the process
