small off-road vehicle for camping/road trips

Hi, I’m looking for an off-road vehicle, which should primarily be used for road trips and camping, but also occasionally in everyday life in Berlin. The following requirements: – small. In Berlin everything is far from impractical; must also be suitable for max. persons – suitable for not too heavy terrain. I guess that forest paths and sandy or stony slopes will be the maximum off-road I drive. – for camping without great comfort requirements g suitable, i.e. roof tent or sleeping space in the interior must be feasible – as economical as possible in consumption (money is a topic as a career beginner) – as cheap as possible in maintenance and low running costs, i.e.: not vulnerable, low spare parts costs, KfZ tax as low as possible. – reliable. I am not a screwdriver and have no opportunity to screw myself in the city center of Berlin. So far I have thought about Suzuki Jimny and Lada Niva. I like the Lada so far visually better and he is not quite so tiny, however there are relatively many horror stories about his susceptibility. For the car itself I plan €6,000, so only a second-hand purchase makes sense. What thoughts do you have? Thank you!
