The two-headed Audi 100 we featured yesterday got us thinking: folks make a lot of odd, sometimes inexplicable modifications to classic cars.

One that immediately comes to mind is a relatively early Fiat 124 Spider that we found in Salt Lake City, Utah, over a decade ago. We unfortunately don’t have any photos on hand, but the previous owner had re-wired the entire car using components sourced from a Volkswagen Beetle. Another strangely-modified classic we stumbled upon more recently is a 2CV fitted with a bench seat — literally. At one point in the car’s life, someone bolted pieces of wood to the stock seat frames.

How about you, what’s the oddest modification you’ve seen? We’re talking something you’ve actually seen in the metal; that red, Ferrari-powered 2CV AK that was posted by every generic car blog out there a few years ago doesn’t count.
