First home hunt: lift ka kya bharosa?

Lift quality aur maintenance response time ka kya scene hai builders ke projects mein? Humne Prestige City dekha, floor 15 pe jaana tha, lift slow lagi thodi. Not sure if it's just that one or common. Kya builders time pe service karte hain ya phir waiting time bohot zyada hota hai? My parents keep saying ki old buildings mein lift ka issue rehta hai, so new projects mein bhi same problem toh nahi hogi na? Bahut confusion hai yaar.
