The key with making things look longer/taller/etc...is drawing the eye in the direction you want to emphasize. For example, on a person, if you want to look taller you wear thin vertical stripes that draw the eye up and down, or a deep V-neck to do the same.
So, if you want to make your car look longer, you want to emphasize horizontal lines and downplay anything that makes it look taller. You could maybe paint in the horiz lines, or try a pinstripe. And as for de-emphasizing the height, bigger rims or lowering it would go miles to make it look longer.
I can try some photoshops, if you can send me some bigger pics (it'* way too hard to work on pics even that size, at least for me), like at least 800x610 (or whatever the ratio is).
