Discovering that the car is not in a good condition after buying it. What to do?

Good afternoon,

I bought a Lada car in Ras Al Khaimah last Saturday. I tried the car there, no particular driving issues. I went with a friend more specialized than me in mechanics, he didn't notice anything when opening the hood.

The owner came with me to Tasjeel in order to do the transfer of property, so that I can bring the car to Dubai (where I live) to have it checked before redoing Tasjeel.

The feedback of the garage is clear: many parts are rusty, paint was redone and anti-corrosion applied, the car may have been flooded. Also, the engine is cracked.

I contacted the seller (an Emirati), telling him that he did not mention all of the above when we met on Saturday. I offered to bring back the car to Ras Al Khaimah, and redo the transfer of property at my expense which he refused.

May you please help me to know what are my rights in that regard? I search on the internet and came to know that a New Consumer Protection Law of UAE was recently published.

Thank you for your help!
