Not British or a V8, but British inspired and sweet anyhow:

A bit overpriced, mind you. :)
Like the colour. I always like maroon, it was big in the 50s in the UK, but faded rapidly both in colour and popularity.
There was a Rollerskate on BaT iirc, umm, here it is/was https://bringatrailer.com/listing/1991-maxton-rollerskate-3/ made $14,650.
Not as shiny as the one you flagged.
Imagine they would be fun, even more so with a V8.
