Right to exist?

So, my Ford Sierra CLX: nen 91 ́ 2.0i DOHC with 88/120 “Coupe” silver So this is my beloved car, which has been faithfully accompanying me for about 2 years now. I bought it at that time for a whole 300 Euro with a mileage of just under 100tk. Was in very good condition and was cared for and loved by a pensioner. Now I have smoked the engine three days ago, suspicion of cylinder head seal. Unfortunately, the seal was still perfectly in order, so the problem must probably be some crack in the head?!? (“I don’t really have a specialist man”… Now the question arises for me whether I miss my car another second life again. He has meanwhile well 140tk on the hump, the brakes and shock absorbers have to be made in the near future. He still has about a year of TÜV. From the emotional side this question does not really ask himself, because I like my car, it’s just hanging on it and it’s just good… but he is a 2 door and of course I don’t have a chance to get the money?
