It's totally worth it if it's for your own stay. Imagine that u getting a second car, where r u going to park? Rent another parking or park outside?
Or hv your own parking inside? U enjoy the convenient parking inside with security and probably covered car park. Your car being protected by security and also from the unforgiving sun and rain.

If u park outside, once your car got broken into, say u lost RM500. It's heart pain n $$ gone for nothing. Not forgetting the hassle of going outside your condo to take your car in the rain.
