Time to sum up:
We know that the car is "very much European", I assume that a state outside the EU but inside or rather close to the geographical borders of Europe is meant or it is one of those rebadged Hillman Hunter / Morris Oxford things that have been made in Pakistan or India ages after production stopped in Europe.
Furthermore,we know that it is not:
- Austin Metro
- Fiat 126/127/131
- Ford Fiesta
- FSO
- Lada
- Mini
- Opel Kadett
- Reliant Robin
- Renault 5 / 12
- VW Polo / Derby / Passat Mk1
- Yugo / Zastava
There really shouldn't be that much left now :? Hmm, Seat 1200 Sport perhaps?
