Tata Motors — rust on engine and vehicle run was 200km when delivered

Address:

Lucknow, Uttar Pradesh, 226005

I have bought tigore xz revotorq diesel from dealer: motor sales charbagh, lucknow on dated: 08.11.17. Vehicle delivery was done by 8pm so i was unable to look into engine. Next morning when i saw engine there was rust everywhere (Even on bolt heads). Also i noticed that vehicle run was 210kms. My home is around 5kms from showroom. I have discussed with gm of motor sales charbagh and he answered me that rust is on every vehicle of tml and also he said that 190kms run is also normal by the time of delivery of vehicle.
I want to ensure that vehicle engine and other parameters are at correct parameters. Please help.
