Keeping or scrapping Audi 90??? What should I do?

Hello Audi friends, now I have to choose: because of TÜV I have to decide what should happen with my faithful 22-year-old Audi 90 2.0E. I bought it in 1997 with 130000km and thus drove 455000km km, now he has 585000km on it. Falling work: exhaust endpot, summer and winter tires down, recently long brake pedal path (I suspect brake power distributor), cracking on the front axle (broken spring vlls?), AU possibly problematic (run long without lambda probe), Crack in headlight glass and fog glass. Everything is not bad, but the repair costs exceed the residual value, which is full of 200 euros. And besides, he is now a damn ugly box. Last summer he also got two really bad hail damage. Even my boss once mentioned to me that this car does not exactly do well in the parking lot in front of our practice. For the car speaks: a. uniquely reliable. Drive it since 13 Jah b. the mileage of 585000km and that with zero oil consumption, first clutch and scratch-free switching of the first gearbox c. I hang on to it because it has served so long faithfully and I have spent thousands of hours of my life in it. d. it has D3 and swallows between 7.5 and 8.5 liters of replacement I would have now already for a BMW 525. There would still be the possibility to use it as a winter car, but then I would have to repair it anyway. Guys, what do you think???
