Sales - They will assign advisor, till delivery everything will be fine post that advisor will be always in meeting only to your number. Not sure how he is reach the target in his busy meeting schedule. Service - If its free service they will keep the car for some time then with lubricant they will give touch-up, if any complaints they will fix they wont clean it properly... Accessories - Only after payment they will process and fitting will not be proper and safe too... better go out side they will good experience. Co-ordination between the different team will happen like government office. Only with help of owner its possible. Buy vehicle from other showroom if you need co-operation if you consider its your showroom means once u leave the vehicle for service you need to tell them what it needs to be done after that check all things are properly done or not fitting proper or not...
