if you talk about the latest version, the front design is different, and Alphard uses solid color rear lights, while Vellfire uses transparent rear lights.

interior is the same, except 3.5 is different from 2.5.

because driver used to driving kancil will have hard time driving such big car?

Starex, is bigger or same size as Alphard...

Innova smaller.

same car with different front design & rear color lamps.

the 2.5L is fabric seat while 3.5 is leather, and the gear console is full piece on the 3.5 while 2.5 middle area is empty.

when you say sampan, obviously because it's tuned for comfort, both Estima & Alphard/Vellfire uses Van platform.

you want stability & comfort get Mercedes R Class, but it only has 4 doors.

you want better handling, Honda Odyssey is a good option.

Elgrand will drive like Alphard because it's tuned for comfort.

Innova/Avanza is just like Exora.

Nissan Serina is abit like Estima, less space but better drive.

you don't expect a van to drive as good as a car.
