Do you think it's strange if I give up my apartment and sleep in my car?
It seems strange, why would you want to sleep in your car?
Apartment rents are ridiculously high and I want to save that money towards a house. Sleeping in my car would be free.
Sleeping in your car isn't very comfortable and you shouldn't do it if you don't have to. Consider looking for a roommate to share the high housing costs.
I think it would be fine, my car is comfortable and I'll save lots of money this way.
I know you want to save money but sleeping in your car is not healthy or safe. Someone could rob and injure you and it's not sanitary because you don't have access to a bathroom. Your car is for transportation, not living in.
