Was literally in that situation back in 2018. 110 mile round trip daily commute, ~$500/mo in gas. Had to fill up every other day.
Bought a 2017 Ford Fusion hybrid and cut my monthly gas expenditures down to about $200. Payments were about $225/mo so I ended up saving $50/mo once the insurance differential was factored in. A tank now lasted me just over a week.
As of 2020, l’m still driving it, but I’ve since moved much closer to work. A tank lasts me about a month now.
As of 2021, I work from home. A tank lasts me 3-4 months on average. Car is paid off.
