Pune: What really happens to promised amenities?

Visited Kohinoor Famville last Saturday and the show flat looked amazing, but I'm honestly a bit nervous about the reality. The brochure showed so many amenities – a huge clubhouse, sports facilities, green areas. My parents keep saying what's shown isn't always what you get, especially with construction quality after a year or two. Are there common issues like cracks or seepage in newer projects? I'm also wondering about maintenance charges. They quoted a figure, but is the service quality actually good? Or do these facilities just become ghost facilities after a while? For a 2BHK, it feels like a big commitment. Ab samajh nahi aa raha how much to trust the initial presentation. Any experiences with Kohinoor projects or similar situations in Pune?
