There was a question a few days ago here, someone coined what could be the biggest problem with economies. This is one of them, for sure. People can't differentiate assets and liabilities. They think they own the house, they claim they own the car, and in the meantime they're in utter debt. People strive to take on liabilities instead of building wealth which consists of assets (favorably hard or income-generating assets). They discount their time, become corporate slaves just to keep up with the illusion of their lifestyles they ought to show to the outside world.
And I see this everywhere. The four of us in the room all came from the same school. Same age. Same opportunities. Three wheeling in heavy debt, trynna keep it up with side hustles. One with a positive balance who never needs to be a corporate slave again.
I don't know why exactly your friend asked if you have a car but there are some business that required you to have car, it package you and your business to your clients. If that's why he was asking an feels there is a need, then he is right but if they are asking because they know you are doing well financially then they don't know what financial brilliant is about, they afr financially ignorant and they want to sink you to their own hole of no return, don't think about their questions.
I can be wealthy and doing well but it doesn't necessarily mean I have to copy another person lifestyle or what other people thinks about wealth. When I was struggling to put things in order and make my investment successfully, there wasn't anyone and nobody was there with any suggestions to make it successful. Now that you are doing well, they now think they have a say in what you are going to do, then that's very wrong of them, I will advice you to ignore them.
