Based on your budget, no doubt that inspira is the wiser choice.
Mitsubishi engine oil is rm100 per 4L
Cvt oil around Rm200 per 4L
Oil filter around rm20
Air filter rm10 (bosch)
Aircond filter rm30 (bosch)
Brake oil (similar with others)
Brake pad, I propose stick with Akebono. Mine at 140k km still have plenty left (wise driver)
Disc brake replace with trw if anything happened rm300 per pair iirc
Water pump Japan oem rm250
Aircond belt rm150 mitsuboshi
Spark plugs iridium rm180 for 4
Absorbers less than rm1k for all 4
Tires,depends on size.. 215 55 17 starts from rm250 per pc
Wow, that's actually not that expensive so it's good news for me.
Anyway, I am not in rush of buying the car yet, maybe early next year when my sis is graduating so I can throw my current car to her while waiting the age count of current cars to increase by 1 and hopefully drive down the price by a few thousands.
