Yes but we cannot look down at other car brands for not having a reputable audio system. On the contrary, they do. Our Proton X70 has a Kenwood system with a factory sub-woofer and the Haval H6 and our Julian comes with a Harman system. Don't know about Glory 580 or Oshan X7.
So, yes, the sound is good but it is not the only kid in town with a branded system 

Road noise insulation is good on the Tiggo 8, but the Proton X70 is next level quiet. But as far as power or 7 seat accommodation is concerned, Tiggo 8 is the king in our stable. I have to add that the Tiggo 8 is the "go to car" in our household when it comes to long distance traveling. Not the Proton or the Julian.
Yes, it is fact that people look at resale values and many times it is the most important factor in choosing a vehicle. It is not that one is buying oranges for a hew hundred rupees and if they turned out rotten, one does not feel bad throwing them away. When it comes to buying a vehicle costing a 100 million or more the comfort of knowing that one will be able to get back a substantial amount of that 100 million back cannot be frowned upon. So some people will put up with a khota ride in exchange for the comfort of knowing that their money is safe. Toyotas world over (Middle East, USA, UK, Asia) ALWAYS retain value.
