Premium 3BHKs in Pune are a resale nightmare, fight me

Honestly not sure if the premium for a 3BHK in Supreme Towers Phase I is justified for an investor like me. I'm currently in a 2BHK and thinking of upgrading, but this price range (₹3.31 Cr+) is a big jump. My main concern is capital appreciation. Has anyone tracked its price movement since launch? Is there still significant upside left, or are we near peak? Also, what's the resale market like for properties this high-end in Pune? Is it liquid? I don't want to buy into something that's hard to exit in 5-7 years. Any insights on the builder's delivery track record would also be super helpful. Already have a home loan, so need to be smart about this investment.
