Jimny is a 2-door 4 seater with limited space and small luggage space. It's got the same engine as Suzuki Swift and it has 4WD. The vehicle itself is not common and spares are not easy to come by. Terios on the other hand, is a 4-door car and its more spacious. Hence, it is more common.
Sooner or later, the suspension of Jimny will go bonkers and you will have to shell out about 30-40k for repairs.
You can get a Terios, Cami, old Vitara, Maruti Gypsy, Pajero Mini, Zotye Nomad 1.3 for that price range.
If you want to look cool in a vehicle that pretends to be a JEEP, please don't ask about fuel economy. None of these will do more than 8 to the litre.
If I were you, I will try to get a Perodua Kembara. It's same as Terios except for the front grille. But its made in Malaysia. I would use that as a bargaining point to grab one for about 1.5-1.6 million.
