Yes, welcome to the forum. 12000 euros sounds expensive even for an A2 with only 55,000 km on the clock. Sure, it depends on specifications, but as a baseline, two years ago I paid €8000 for my 2004 FSI SE S-Line in a private sale. The car is very close to full specification and had less than 35,000 on the clock at the time. That was in Belgium: don't forget the EU is a single market and you can buy in one country and import without hassle into another.
No serious issues with it yet (now on 65,000 km), except for a sticky engine management warning light which was eventually (and rather expensively) traced to a bit of corrosion in the wiring. It certainly prefers 98 octane. Average consumption on a 2500 km run down to Bordeaux and the return with my own modest weight in red wine was 6.1 litres/100km at an average speed of 66 km/h, mostly long-legged French country roads - declassified Routes nationales - a little heavy urban use in Bordeaux itself and some hard slog on the motorways.
