No offense but kindly note that, the point of reliable you raised is related to Engine and mechanics (gear box etc) and these are imported as it it. Indus is not assembly them here.
So, rest of the build quality should be focused. Low quality paint finish, low quality plastics, not properly fitted parts like gap in dashboard, center console, body is also inferior
I am not a fan boy of Hyundai or anyone. I have used Grande, Civic and Elantra and if you want premium and better finish, you can check and your answer will be Elantra, rest reliability, Elantra is sharing same engine with Tuscon and Sportage, so they have trust on it.
Lets the time decide it else we will be like a ball between Indus and Altas forever
