Financing / leasing or continuing

Hello, I’m about 30 years old and I’m an electronics technician. I’ve been working at my current employer since last year, I’m still in an open-ended employment contract. I’ve been driving my old Audi A3 8L for a few years now, he’s been doing me good services for the years, but slowly the mistakes, the chassis is causing problems, although many things have been exchanged. Now I’m looking for a solution to get a new mobile kit. And on the market there are different ways to pay for such things In the moment, there is about 5000 euros on the savings account. To the car: Combi (passenger class) from 130 kW decent equipment Budget 500 to 25t depending on the car I drive about 50 km to work (back and forth). I come about 15tkm a year. I earn an average of 2200 euros net as salary, this often varies up to 3000 euros, if I make overtime or additional shifts, and of course Christmas money and holiday money. eld. My rent incl. ancillary costs and internet and television is 400 euros per month. In addition 160 to 200 euros for food. If I set my maintenance at a flat rate of 900 to 1000 euros is in any case generous. What kind of purchase of a vehicle can you recommend to me?
