I bought 2022 Innova X after considered & test drove several MPVs:

Aruz
pros: cheapest, good FC, easy to maintain
cons: underpower, too much body roll during cornering, lesser space than innova

KGC
pros: spacious interior & boot, diesel powered, good FC
cons: cost (price 180k, road tax & insurance 4k/yr, suv tyre 2k/change), too huge & wide for malaysian parking spots

Xpander
pros: nice exterior design, high ground clearance, good FC, easy to maintain, drives like a sedan
cons: lesser interior space than innova, 2 airbags only, no 3rd row aircond vents

Serena
pros: sliding door, spacious (low floor & high head clearance), clever boot mechanisms
cons: price 158k, slow pedal response, very noticeable body roll, tiny 360' camera display, common absorber & compressor problems

Innova X...IMHO this has the balance between all those other MPVs
pros:
- price 130k, road tax & insurance 1-2k, 17' non suv tyres below 2k/change, more available spare parts
- 7 airbags, tough ladder frame, high ground clearance
- refined ride comfort, lesser body roll than serena, third row aircond vents,
- toyota- a brand well known for reliability & toughness
cons:
- underpowered engine thus high FC- laju-laju nak pegi mana? minyak lebih kurg exora je..i can tolerate rm100/week for petrol...proper gearing will do for overtaking..
- high floor- now there are running boards available for innova x
- less boot space- i already installed roof box

5 months...booking in Dec 2021 & delivered May 2022...lucky to have booked during tax holiday

New Alza was only a rumour during my survey...but I will stick to Innova anyway because of higher ground clearance..
