House without a doubt. As others said, you need a garage first.
Though warning for first time home owners, be prepared for move in expenses (furniture, appliances, decor, etc). And if you're moving into an older home, repair/replacement costs. My plan was to wait a year before getting a new car, but ended up being 3 years after having to replace the HVAC system and installing double pane windows, plus other unforeseen expenses. Even then, those upgrades are an investment in the house.
Still, part of me wishes I'd bought the Z sooner after finding out how much fun it is to drive
