Stable income: Somewhat stable

Car wrapping and mobile advertising can provide a moderately stable income source for individuals. While there is a decent baseline income, it can be unreliable at times due to fluctuations in demand and competition. Some months may be similar, while others could be unpredictable. I'd rate it a 2 out of 3 because while it can offer consistent earnings for some, there are factors like market saturation and seasonal changes that can impact income stability.
