Bad roads suitable cars?

Hello dear Offroad Forum, I hope you can help me. I will soon have to travel on forest and field roads more often. Can you give me advice which used car would be particularly suitable. To buy an off-road car I fear because of the high costs. What do I have to pay attention to in general? Suspension, suspension, ground clearance, spare parts prices? Would be nice if you had recommendations regarding brand and model for me!
