Hello dear motor talk community! The following case is presented: I was offered an offer for a 964 Carrera 2 BJ 1990 90000 km. To be specific: 10000 – 12000 Euro. Before the question arises: Yes the offer is seriöus, because the seller is an acquaintance of us (KfZ-Mechaniker). He bought the car very cheaply (cylinder head seal was probably broken), but now builds it up again completely, or lets the important things at Porsche do (knows there probably someone Well, so far everything sounds great, but now the big BUT comes: I’m only 18. It’s not as dramatic as it sounds: Since I’m active as an actor, I have a monthly income not to be despised. Now the question arises, however, what I have to pay for maintenance – the purchase price is just a part of the whole thing. You can let out the insurance price now, but what else comes to me besides petrol costs? How much KM does an inspection have to be done and what does it cost in a PZ? Which factors are still to be considered? Thanks already for the answers
