see if you have time, and if they are good enough to hand over in few hours, stay back and try to meet your SA and make some healthy relationship with him, its always helpful at tata motors if youknow SA.Try to discuss things about your car with him, issues, things you liked, disliked which makes your ownership much more easy and fun.We usually hand over keys and go away, and keep complaining about their shabby work, atleast know him eye to eye, sometimes take out time as well, which makes them to believe your belief in their work as well which is a part of ownership as well.
IMO.
