With many people, u need torque. Go for diesel MPVs.

Try Hyundai Starex which expensive at RM 140k. End of the day, u save a lot with diesel because FC is very good. A typical 2.5L truck / MPV can get 600 to 800km per full tank depending on driving style.

Or cheapest is a Renault Kangoo 1.5DCi. Normally available as commercial, 2 seater or 5 seater only but if u ask the salesman at Tan Chong nicely, they have 7 seater version for sale too. Price is around RM 50k to 60k.
