My Dwarka Expressway site visit: Hidden charges reality?

Visited M3M and Godrej projects recently near Dwarka Expressway. From my experience, construction quality differs. M3M ka finishing better laga. But Godrej projects mein hidden charges kaafi sunne mein aaye hain. Is it true? Kya kisi ne actual possession par unexpected costs face kiye hain with these builders around Sectors 102-113? Curious about post-possession surprises.
