Success has broad and subjective goals. Generally, if the goal is to build wealth, it means you've achieved a career or goal that can create wealth because you have a source of wealth from the career you've built.
And if you've achieved both, there's no harm in buying what you need, like a car if you really need one. I think it's important because a car can be a means of transportation for traveling or for essential purposes. And you should also own a house, which I believe is far more important than a car, because a house is your shelter and a place to rest. After all, people will judge you as successful and wealthy if you already own a house, and vacations are also important for refreshing the mind and reducing stress. And more importantly, you must have assets or investments to maintain your wealth and success in the long term.
