Model Factory Hiro produces a beautiful and expensive 1/12 kit but now out of stock .
They occasionally re issue kits so you have to watch their site. They also come up on e bay from time to time but, again, expensive.
I have one bought when they were first available and like most of their products it sold out very quickly.
If you are unfamiliar with their kits I can tell you they are amazing,but again, expensive. Here is a link to a build log of my Alfetta a few years back …
And a link to MFH site re: Barchetta.
