Help with buying a used van.

I live in Hungary in a poor little village in Álmosd, in April 2020 I lost my job due to the COVID-19 virus, I was unemployed for months. My little son was born in June 2020 and it gave me the strength to start my life again. I started a tiny business, taking advantage of the quarantine situation for local people to get disinfectants and cleaners in a person’s car. The idea was good, but the car was not. That’s why I want to buy a reliable vans and ask for help with that.
