Consider a cheap car only if you need the cargo. Something easy and cookie cutter such as a honda civic. Parts and repair are cheap on those cars, especially the 4 cylinder engine ones.

Something from A - b with little to no cargo space, cheaper option? Probably go for an automatic motorcycle, the scooter kind has some alright space, gas is super cheap when riding them. Insurance is also cost effective compared to cars.

What about public? Sometimes your local city or county will have public trasportation services. See what runs and the times that run. If you taking uber/taxi then im assuming public transport is also an option. You are trading time for cost on this option as there are wait times for the bus and such you take.

No public transport but the job is somewhat close by? If the route is reasonabley close, try gas/electric powered bike. Hell even an electric scooter. But be mindful of your road conditions. This usually plays into the type of one to buy. Try going over potholes or bad roads with thin tires and no decent suspension. It sucks. Also is public safetey a concern when using at your location or near the job? If yes then probably sticking to the above options might be your best bet.

Hope it helps.

Ps. Buying a car and selling it 3 months later is a financial hit . you need to pay for title transfers, taxes and any other misc an owner might have not disclosed to you before you bought it if you bought privatley. Used and new dealerships also overcharge. Cars are too expensive right now but depending on your location, your mileage may vary.
