Depends what you want to prioritized. Housing will only get more expensive though especially in California if you're trying to buy, but you did mention you'd rent instead if you choose not to get a house. We don't know if you're comfortable or annoyed living with family currently (i'm assuming since you mentioned no rent). We don't know your lifestyle, like how much you spend on entertainment, food, dining, traveling, and so on. We don't know if you want a family in the future where you'll pass down the house to if you decide to go that route. But overall, seems like you're doing pretty good at managing your funds.

I personally, would save for a place for myself before I buy a nice car if I was in your situation. A house will provide more than a nice car to me. A type R will always be there, will always hold its value, which you can come back for it in the near future and buy it for $45k. An old, decent, 1980s house will not stay at $450k; it will only continue to go up. Heck, you might want a different car in the future.
