I was sold a used hand car in POOR condition

I recently bought a premium SUV car from a used car dealership, I am the third owner of the car. I bought the car for 8.5 lakh rupees but have already paid almost 1 lakh in repairs. I was promised that the car was in working and good condition. But not only is the car an absolute hazard on the road but it's transmission too has now broken down and is estimated to cost me around an additional 2 lakhs. I have been stranded in the middle of highways and roads multiple times already because of the serious problems in the car, I could have been involved in multiple accidents because of how the car has broken down in the middle of the road. I have paid for multiple repairs in just 4 months of owning the car and now apart from the transmission repair, there are more repairs required including changing the shockers, which is another hefty cost. I want to take action against the dealer and the owner for concealing information about the serious repairs required. What action can I take and is it possible for me to get my money back? If I do take legal action will I have merit in the case?
