its actually an S3 (1987 model)
However, the one EU country that has exhaust gas emmission zones for CARS (in other words you need a Kat to get the Euro4 green sticker) is only really Germany, and that is mainly for big cities.....you can still drive it in the countryside

............though that defeats the point, I agree!
France, Spain, Portugal, UK have no emission zones. (well London has a zone, but it is only for lorries)
Italy have some zones for cars
Holland, Austria, Sweden and even Denmark etc, only have the emmission zones for lorries.
- or wait till 2017 when it becomes a classic or historic vehicle, then you can drive anywhere
