It was all fairy dust. Evoluto Automobili were apparently working on a singer style F355. Never came to anything outside of internet hype and bad renderings.
That's what I thought but this might be something newer, more recent, UK based. My source works with Singer as well as the wider industry - I'll try and get him to give me more details (over a pint or two probably)
There’s already a few guys making their own personal version of the best F355 - I can think of @INTMD8 and @OCKlasse for example. There will be more, I’m sure of it.
