Maintain Ford Probe?

Hello, I have a question. And I find the Ford a very nice car. Could also imagine driving it myself. But now it comes. My father friends and relatives think that the car would eat me up on the maintenance. So I drive on 70% and have calculated that I would pay on liability 700€ annually. So much more than now it is not. If the Euro2 standard is met, they are also icht so high. Have read that the 2,0l should be more stable and would also be completely sufficient. Ask yourself what reperatures so cost, but most of them I will do myself anyway. With a consumption of 8-10l in normal operation I go out. So now I ask you, is the sample really too expensive for me? Is it so expensive in the maintenance?? Please report your experience.
