Maciek Grabowski writes from Poland in July 2007, saying:

'I've met this R4 in Warsaw at work (I'm delivery driver in "animals stuff shop" and I drove my R4 in that job).'

Maciek's own 1985 R4 F6 C1E can be seen in the remaining pictures. It runs on LPG.

You can find further photos of Maciek's van over at number PP236 in the People's Pics section, where it was seen crash-damaged back in February. Maciek informs me that he's since done 1,500km in it following repair work.
