Die-cast Audi cars, Hot Wheels, or mini brick car models in Mumbai?

Hieyy people of Mumbai! Looking for a birthday gift for my car enthusiast BF. Where can I find die-cast Audi cars (MINI GT) , Hot Wheels, or mini brick car models (LEGO-like) in Mumbai or even Navimumbai ? (Adding pics for reference) Can anyone please suggest where I can find these in Mumbai? Are there any specific stores or markets that sell these types of car models? I've checked online marketplaces, but I'd love to explore physical stores. I’d be super grateful for any help, thanks <3
