I am sure i am going to get some stick for my following comments, but I have no intention of insulting anyone.
Why would any one want to spend time,energy and maybe money on renovating something that has no prestige, no heritage, no quality and rides like a garden gate.
A Raleigh from the special products division I could understand or, e.g. the Chopper bike, technically pretty shoot, but in its time it had a style of its own and a place in history, This Europa thing, while not rubbish was really nothing special.
I suppose if it was the first proper bike you owned or something like that I could understand the nostalgic interest, but please, it was a cheap massed produced bike when new and whether you wish to ride it or admire it, just because it is 30 years old doesn't make it right. .
If I could get my hands on an original 70's Holdsworth Pro and restore it, that would be something to get excited about. Although mass market to a degree, it has a heritage from a legendary team.
I can't get the slightest bit interested in this Europa, I don't get it. Sorry.
