How much does a Sonic owner make a year?

I'm curious, could you please elaborate on the potential income of a Sonic owner in a given year? I understand that the Sonic is a popular vehicle, but how does ownership of one typically translate into financial gains or earnings for its owner? Are there any specific factors that might impact this figure, such as the model year, mileage, or condition of the vehicle? Additionally, are there any opportunities for owners to generate income from their Sonic beyond its primary use as a mode of transportation? Thank you for your insights.
