Because its SUV, comfort is lesser compare any MPV.. Estima i can say the best comfort level for MPV, spacious too..

but maintainance can be on higher side, with 2.4 engine, recond, 17-18 inch sport rims and many more.. i end up with Sienta with smaller engine and it size similar with Alza but much more spacious and premium.. Sienta is true poor man Alphard coz have power sliding door for V n G spec..
