I was looking at this photo montage and I realised I need a life, because I can tell you:
- from the rear bumper shape, wing shape, badge positions, rear grill shape and rear deck lid shape that they are all Roadsters.
1. the top red one is all original, with no mods. It's a '99 open light car. I can tell that from the badges it has (bull badge, followed by the Lamborghini script on the left and VT on the right).
2. the yellow car is an early 96-98 pop-up Roadster. You can tell from the bull badge in the middle (which is larger than the small bull badge on the '99 car above) and the VT on the right. He added the Lamborghini script on the left for balance. He also painted the rear tail light surrounds to match the body colour and added Diablo 6.0 tail-lights. The naked CF wing was an option on the '99 cars, not earlier. He's got a rear camera fitted to the rear number plate plinth and those stupid blue lights in the white reverse lenses.
3. the black car is an early 96-98 car (you can tell from the badges) and it has the rear tail light surrounds painted to colour match the body. Also the Diablo Roadster badge on top of the rear lid has lost all its paint as it's silver.
They are all US cars - only the US cars had two white reverse lights in the rear bumper. All other countries had a white reverse light and a red fog light. The reverse light is on the side of the car closer to the curb (RHD v LHD).
You make something idiotproof, they'll make a better idiot.
