Car for 36 months

Hello I am more or less facing a problem. I am currently driving a Micra, BJ 1997, 195000 km and slowly but surely no longer fit for driving. With my current employer I am on 1 June out of the probation period and come into an indefinite employment relationship. My job is all of Germany. The problem now is that I need a new car, but probably only for 36 months, because after 2-3 years in the job you “rise” and get a company car. So now go a new car doesn’t make much sense for 2-3 years. But if I were my favourite, because I have dealer warranty here and have 3 years rest before repairs, TÜV etc. (could have been). A used car would be in question, whereby I would of course like to have a “stupid” car and they all commute so between 15-20,000 euros. So also an amount that I would have to finance. On the other hand, I wouldn’t have to take a dienstragen right after the 3 years, but could then just w I would have a maximum of 8000 euros, but then my whole “cash money” would be gone. Finazing is actually no problem, because the mileage flat rate to my salary will be transferred on average 400-600 euros in addition every month. I’m looking for a good plan to buy a car without destroying unnecessary money (almost a contradiction in itself, I know 🙂 ) Maybe you still have good tips or ih r was in such a situation and can help me. Thank you very much!
