I guess it all depends on what it is going for, and what is REALLY wrong with it. Might not look like much, but if things like gearbox and the like also got damaged, then that will cost. It does not sound like you are in the trade, so unless you know some one who is, labour costs will add even more, plus you are going to want the work to be done by someone who knows their way around that model of car, as there are always going to be little caveats that a general mechanic will not know.
You only have to read through some of the old threads to hear how even Audi have messed up a few basic services, let alone repairs.
Try to get quotes before hand, but you wont get much until some one gets eyes on it, so is it worth the risk, or can you drop a few more notes and get something you can drive right away?
