New parts build?

[CaptainCrash1971]

Daft question, has anyone attempted to build a roadster using all new parts to try and get a new plate. Is this even possible? I know it goes against the build on a budget theme, but wouldn't mind a car on a 10 plate.
I know the engine management would be quite pricey to make sure of passing IVA but can anyone see any other massive expenses?
It's only a pie in the sky idea at the mo, I'm still actively looking for a donor whilst dreaming.
