Cost check e92 325i?

Hello, I've done a rough estimate of my monthly costs if I were to get a 325i. Is that about right? Thanks in advance.

Tax

Approx. 200€-》approx. 17€ /m

TÜV, inspection,

Every two years, you don't really need an inspection for such an old car, do you? Anyway, -》 about €25/m

petrol

1000km per month, 10L fuel consumption? (?)

-》approx. 220€/m

Insurance

Since this would be my first car, it's correspondingly expensive. Even as my parents' second car, it's about €1,200 a year -》 €100/m

repair

50€ per month(??)

In summary, I'm coming up with about €400 per month. Is that realistic?
