Itna pareshan nae ho bhai.
Their have always been 2 types of Jimnys. 660cc and 1300cc.
Some cosmetic differences. PakSuzuki imported manual 1300CC base grade Jimnys in Pakistan only.
660cc Jimnys are mostly automatic. As I mentioned earlier those are toy cars. Replacement for Suzuki Alto, Nissan Days, Daihatsu mira and other 660cc cars. Higher ground clearance might be an advantage, turbo might be fun to drive. But these 660cc dinkies are not meant for off roading.
The 4x4 in these small cars are for snow driving in Japan.
Suzuki Jimny 660 is usually called Jimny or Jimny 660.
Suzuki Jimny 1300/1500 is mostly know as Jimny Siera and has a wider body bigger bumpers.
Similarly Mitsubishi mini Pajero is 660cc Pajero Junior or JR is 1100cc
