Salarpuria Sattva Shamshabad: Is the quoted price the final price?

Shamshabad mein Salarpuria Sattva ka ek project dekh raha hoon. I'm based in Dubai, so site visit ka issue hai. They quoted a price for a 3BHK, around ₹2.2 Cr. But I'm trying to understand the *all-in-cost* better. Builder bolta hai yeh final hai, but I know there's stamp duty, registration, and PLC. Kya parking aur interiors ke liye bhi separate charge hota hai? Kitna extra add karna padega on top of the base price? Pre-launch offer pe gaya tha, but I'm not sure if it's actually a discount ya bas marketing hype. Has anyone invested with them recently? What was your final acquisition cost like? Need a clear picture before deciding.
