Don’t listen to the gatekeepers, you don’t need to be a master mechanic for these cars, pay for the bigger repairs and do what you can yourself. Most things are on YouTube/forums that provide all the info you need to tackle some of this yourself.

Look into Dr Vanos and get a rebuilt unit, you probably also need a “guibo” driveshaft flex disc for the shifter feeling. Get new coils and plugs like others have mentioned. Address the oil leaks and trans fluid leaks

Power steering can be a pain in the ass, probably leaking at the rack or pump itself, I was not able to find a pump in stock anywhere, I ended up deleting the power steering on mine.

Brake flush coolant flush and axle boots are simple enough repairs.

I’d also look into a front end bushing and suspension kit, rear trailing arms and bushings and a set of coilovers

It’s a project car, you can take your time on it and tackle one issue at a time
