we own a 2.4 previa.... 5-6 km a liter but i bet the alphard would consume more petrol

it is comfy but i bet the alphard is more comfy

maintenance just follow the pms and you would be fine plus matino naman kausap toyota pag dating sa warranty since they know that you bought a quite an expensive ride and would want to retain you as their client.

when our previa was still under warranty i drove it like as if there was no tomorrow- so if anything broke down toyota would replace it(broke the shock a couple of times) but now it's out of warranty i drive like a saint and it's still serving us well
