Car financing (balloon) is that possible?

Hello together, I hope you’ve started well on the Whitsun weekend I turn to you as I want to get some different advice on my financing. I’m interested in a ProCeed GT (though I thought of a new EU car is a good idea but the missing beeper at the front, warranty games and co. therefore I buy a German model). Price is for a used one from mid 2019 (i.e. already MY 2020 ) at approx. 27,000 TEUR. I have made the days a current list of my fixed expenses and this looks like this: 400 EUR rent warm (i.e. with GET and everything), 150 EUR saving (Fond), 60 EUR saving (Bausparer), 100 – 125 EUR food purchase, 50 EUR repair flat fee car, 200 EUR petrol, 100 EUR insurance -> 1,085 EUR total. In addition, there are about 300 EUR for going on, clothes, and things you can yourself The 500 EUR currently remaining land on a daily money account and are currently used for holidays and co. My partner is also working, children are undesirable in the medium term. Now for financing: Planned: 2500 EUR down payment (to press monthly rate), 300 EUR rate each month, 9990 EUR closing rate. Duration: 5 years. However, after the end of the financing, the vehicle should be driven on. Of course, I would like more numbers in About 10 years buy a condominium and shoot in more equity there. Now to my actual question: Is the financing so reasonable or would you adjust something?
