@simon: No, I don't have a R4 yet. Currently I don't have any oldtimer at all. I drove a Volvo 244L when I was 18. I had a Renault Goelette (one of the few with diesel and RW drive instead of 4x4).
I'm searching this one back to know what happened to it. Last thing I found in the beginning of this year is that the Goelette is either in Kent or Cork (Ireland)
I posted a thread about it in the section R5&6 and other renault classics
