You didn't tell us where you live - information that can affect the market for the car.
However, entering kbb with my zip code, a car with that mileage is worth about $7600 in "fair" condition from a private seller - which is perhaps the best it would be rated now.
Plan on a minimum of $550 parts & labor to replace upper front strut seals, if that's all that's wrong. Arnott offers new replacement struts that have much better airbags and seals than OE - $800 each for new, $400 each for remanufactured. A new Airmatic pump is about $300, plus as much again for labor.
Since you are doing your own work, you could make the airmatic repairs yourself for between $150 (seals only) to $2,000 (remo) or $3500 (all new).
The exhaust system may need replacement - or just new hangers. $50 to $1500.
Check out the car's electronics! See if the COMAND and nav work; see if the audio system works. It's likely you'll need an entirely new phone retrofit (depending on what you have now, it could run from a $500 to $750 DIY). Check that control switches work (if none of the dashboard switches work, you're looking at replacing SAMs, $600 each and there are 3 of them). Check your window and seat controls (if they don't work, it's door control modules one per nonworking door, - around $300 each).
Add up the cost of problems, and subtract from $7600.
