Capital Athena: Parking and snag list reality?

Since January I've been shortlisting 3BHK flats in Noida. Currently in a 2BHK in Sector 78, thinking of upgrading. Already have a home loan, so this price jump needs to be justified. I'm checking out projects like Capital Athena. My big question is parking allocation – is it still lottery-based or do they guarantee a spot? Also, what's the reality of snag lists post-possession? Do builders actually fix things promptly, or is it just a formality they tick off? Any insights on what to look for during final inspections would be helpful.
