Back in the day when I was a student living in Leeds I had a fairly hot but tatty Riley Elf. This was well before the internet - 1982 ish.
I remember reading David Vizzard's book 'how to modify your mini' also buying the magazines to order parts from e.g. Cars and Car Conversions.
On one occasion I drove across the Pennines in terrible weather to what at that time was one of the largest, if not the largest, store. I think I was buying a new intake manifold.
I'm guessing the shop was in Lancashire somewhere.
Does anyone remember it? It was quite a large unit. For me it was a proper Aladdins cave.
