Wow you have done a great job with that. The rear window reminds me of the one in my 1953 Studebaker. I have seen and driven many Opels while in Germany. They are a Division of General Motors. We had a 2 door 1969 Kadett Wagon. That little wagon ran great and was almost indistructable. Amazingly, the fuel gauge in it did not work either, we carried a stick to check how much gas we had.
