Subaru Repair to Expensive? Is it time to split up now?

Hi, I think it’s time now. My beloved Subaru (Impreza 2.0d) has probably arrived at a point where the remaining value is probably not all too far from the repair costs. Probably the parking plate filter of my Subaru is already full again (after not even 80000km). I had had to renew this at the time 4 years ago when I had just bought it used. Had cost at that time almost 3500 euros. In addition comes a crack in the windshield of the momenta I think I’ve got to get out somewhere at 5000 euros and after that I still have an old diesel with 200,000 km. I think now would be the right time to separate from the car. Also my routes have changed since then. I’m driving mostly short distances to the train station wa I’m sure it’s not good for an old diesel. I really liked driving the car. I got it to my 17th gift from my parents almost exactly 5 years ago. *Sigh* At that time with something under 115,000 km. What do you think? Do you agree? Has the car reached its zenith. Do I get rid of it for a little bit of money? What would you do in my place?
