You i got you now.
My honest opinion is base model looks like a cargo van not ever anywhere near luxury black plastic all over the bumpers, halogen headlamps, no powered side mirrors let alone retractable or auto folding, all black interior with everything small bit hard plastic, very old style gauges in speedometer. All these things especially the hard plastic everywhere make it the opposite of luxury
As for the top model on road cost would be around 6.3 for filer and 6.5 for non filer. In 6.5 you can get a used 2018 Grand Carnival which i believe is better in everything especially the features which even i cant list all of the extras over Grand Starex.
Other countries do actually get luxury even in vans like Grand Starex unfortunately in Pakistan everything gets stripped out bas alllaaay rim and shark fun teena daal k advertise kia jata hai that our car is so luxurious that its even more luxurious than an S-Class
As for the purchase decision everyone has multiple factors to consider what suits an individual and limitations or preferences . Jo bhi khareedi hai its yours and enjoy it
