You don't live in any of those neighborhoods with that kind of money....In general terms, yes, it is enough, but I defined a nice place and how many rooms haha, because the numbers get smaller...
Basically the rent/expensas/taxes is what takes the big number... A car in CABA is another detail, they will charge you more for garage, insurance (risk) but you didn't mention that, so I'm just telling you to give you an idea.
