I'd agree that the Alfa Giulia Sprint GT / GTA is one of the most beautiful cars ever, Jock.
One of those things I always regret not getting when they were affordable. But then I know I'd only have watched it rust away.
Now my idea of perfection would be a fairly standard road Sprint GT but in RUSTPROOF spec!
Maybe a more modern, efficient and *ahem* "reliable"(?) Alfa four pot for regular use, but otherwise standard.
I notice that Totem outfit in the link replace the panels with carbon fibre, so that's a good start.
I wonder if they also rustproof the chassis, sills, windscreen frame and, er everything else for your 400k?
I think I'm in agreement with
@Bonefish Blues, restomods just ain't quite my cup of tea.
There's also this updated Healey 100, but again I think I prefer the original:

This, on the other hand...
