Booked Amaze VX-MT

I just booked the Amaze vx-mt in mumbai, at 8.5L, BH registration, with insurance and basic kit. Is it a good deal?... Do you think I can get it for lesser?

Please help, first time buyer... Also should I do pdi on my own or hire a professional.... I have watched a lot of videos and prepared a checklist... So what should I do...?

Please guide.... If I should not bargain then should I ask for accessories?... And what are some essential ones?
