Odometer tempering of new cars from dealer

So, was planning to get a new car. The dealer was giving good discount around 1.2 L for the 2024 model so thought of going with that , but wanted to check from my side of doing a third party PDI. Once i was notified about the car has come to the stockyard, went with the pdi guy. He had been in the PDI company for long and you could tell it from his explanation about the things. Overall car looked find but I wanted to be fully sure so we went ahead with the reading of car using the diagnostic tool which the dealer was initially not allowing. Turns out the odometer has been set to 40 even though the car has been driven 700+. Confronted the dealer and he was saying that he will sue the PDI guy for false allegation but once i provided him the detailed report he kind of went silent. He later agreed that car was deived while moving across the location without odometer enabled. I was not comfortable to proceed and went ahead with cancelling the booking. So guys please help check the new cars as you never know the new car could turn out to have issues from first day itself. I feeling like there should be regulations on how easily the manufacturers can reset the odometer same applies for second had car market (mafia) which is story for some other day.
