Recently on CarEnvy.ca, there has been quite a bit of talk about one-off supercars – we’ve talked about the Stile Bertone Mantide, the Ferrari P4/5 by Pininfarina, the Rolls Royce Hyperion, and maybe even some other that my left inferior prefrontal cortex isn’t recalling at this very moment. From the way we make it sound, you’d swear that the one-off supercar was a novel invention, but you’d be wrong. One-off cars go back to the beginning of cars themselves, some remembered by history better than others.

Here’s one that isn’t remembered so well. Way back in 2005, the GG50 was designed to commemorate 50 years of design by Giorgetto Giugiaro. He actually penned this design by hand, just like he did 50-odd years ago. 

Can you tell which Ferrari this one-off is based on?
