The Trabants for Icelandic market have strange cockpit assemblings, specially last imports 1985-1987 (the very last sell was in 1988). Old model plastic steering wheel, pre `84 dashboard, but deluxe speedometer and deluxe gadget for low fuel indicator, seats with headrests but static seatbelts.

I am glad that this Trabant still exist, I think I saw it on Google Street View from 2013. If it is the same car, the ventilation panels are be made of aluminium and not black, so it is 1986 or 1985. Isn`t there any indentification plate in the engine section? It should be also a stamp with the month and the year of production at the panel, right from the gas tank.

Seats with headrests came in 1983/84. Since your 601 Universal hasn't the toggle switches it's indeed pre-1988. Do you have a picture of the ignition lock? They changed it in 1985.
Bumper is 1980+ and door handles are 1982+.

Hey! can anyone try to help me identify the year of this one? I'm pretty sure it's not from 1988-1990 as they were mostly imported here from 1970s-1987
