I stumbled upon these pics while looking for something else on internet. It was sold on ebay last year. I know old stuff....

Ferrari 360 Modena Limo
The model was cut in half and stretched with an additional 3 meter compartment made of carbon fibre and can now seat up to 6 people in the rear compartment. Despite the extra weight it is still capable of speeds up to 166mph.

Ferrari of course was less than impressed, and considered this frankenstein vehicle no longer worthy of their brand. They quickly pressed ahead with legal action against the limousine firm for infringing their trademark.
