Did you carry out a car check on this before you bought it?
In the cars defence, It doesn't take much to write off any car now especially an aluminium bodied 20 year old car. The owners, (22) is a bit much but i once bought a 4 year old car with 5 previous owners (3 from same family though). As long as the car is complete and is a runner and you are happy with the price you paid who really cares.
There are only a handful of A2s' out there that are going to be highly collectable in the future, and they are squirrelled away somewhere in a high security oxygen tent prison, only to be pushed out for special occasions.
Most of us who buy these fun, frugal and very well built funky cars actually drive them, and it looks like you have a nice colour to start with.
The pictures don't show much damage with nice even shut lines and no nasty bodywork dents.
Remember, when life gives you lemons make lemonade.
Engine upgrade, long term project or just a reliable runabout (FSI??) either way the car is a survivor, If you decide to keep it.
