@DonSergioMorello: in my German license-plate-collector-forum there someone new, a fan -and I think owner- of a "Made for DDR" GSA. He had posted this Hungarian link: http://rendszervaltas.mti.hu/Pages/Default.aspx?date=0906&ni=138&li=5&rt=2
about the mass-exodus of DDR-citizens in Summer 1989 in Hungaria and the abandoned cars of them.
