I've not seen this posted before, came across this when I was looking for G. Rutka's contact details - not the same name I know, but a lucky find. He has simple large scale 1 page models of a Mercedes Benz W123, Ford Escort Mk1, Citroen Ami 6 and Renault R4 GTL here:

More digging with the WayBack Machine - the Brusino.com website had Citroen 2CV sedans, AK micro vans and Dyane sedans in many colors and model years, plus some other types. The Specials page already has several models to download including a micro pickup! I was pleasantly surprised most of the files can still be accessed at this link, use the top menu to go to each section:

Take note of the name of the file you want (model/year/color), then when it asks if you want to do a search of the whole website, page through the results to select that particular file.
