I reckon the VL has the most aftermarket body parts for it. There is like 4 or 5 differant kits for it, plus the calais bits. People also stick whatever seats they want in it.
I would say VN/VP, VR/VS AND VT/VX. Body kits are lame as ****! The only commys what look "done up" without body kits are VK's and VL's. Lower a VK or VL and put rims on it and it looks done up. Do it to another commodore and it still looks "stock".
