I have no experience of X7, however, I took our Alsvin Lumiere the next day after delivery of the car last month as the driving seat was loose and rattling a little bit. It was a nightmare experience for me. Had to wait 40 minutes before anyone even listened to me. When they did listen, they said they have no clue and seat has to be changed under warranty. Mind you, the car was only one day old. And as expected, they didn't have seat available with them air aik truck kee batteee Kay peechay lagaa Diya hay
