XUV 300 - Good Vehicle but Bad dealers

Had a test drive and liked the performance and features as well but W8 variant was out of my budget, so booked W6 which suited my budget. Waiting period of 3 weeks for the Aquamarine. Vehicle arrived at the yard, so I was excited to see the car before the registration. Went to Yard to check and shocked the vehicle was already run 60+ KMs. Disappointed and checked with dealer about the reason but they don't have any answers and blaming that they received as it is from Mahindra. So checking with Mahindra about this issue and following up. It is suppose to go for registration today and delivery by 6-Apr but unfortunately everything screwed up. Let us wait and see.
