I worked in Zwickau just after the wall came down, it was an "interesting" experience. When the wall actually came down I was in Paris, in the next days there were Trabbies all over Paris, people just loaded up their cars and headed west.
I was there for three months and the place was changing before my eyes. The temperature plunged to -40C one night and froze my water pump. I was in a panic as my car was never sold in the Eastern block. I found the address of a Volvo dealer, when I got there in a cloud of steam it was absolutely brand new and surrounded by equally new dealerships of all major marques but the road to it was still cobbled.
