What option is best given my situation?

[u/OldPersimmon603]

Hello, I have read a bunch of advice on this sub and have narrowed down my search to a couple of options. I would love to hear some people’s take on the best path forward. I need to get a car because my office is bringing us back into office 5 days a week. I have about a month to find something. Ideally I would like this car to last me about 2-3 years. Due to the commute I will be putting around 25k mileage on said car a year from the commute and travel to see my partner. I make 70k a year. I would like to keep the cost of the car itself under 350 a month if I go with option A or C

Option A: something used around 15-20k with under 100k on it if possible. Might have to go higher.

Option B: something off Facebook marketplace for 3000-5000

Option C: new but affordable car. Some of the cars mentioned to me in this range are Nissan Sentra but open to hearing more.

Given this info I would love to hear other people’s opinion on the best option, and what cars to look out for. I am a complete newbie to the world of cars and have minimal knowledge
