<prompt> Human: I am a medical student and we are required to have a car for rotating on the wards. After a year of clinical rotations, however, I am going into PhD so I wont need a car then.I figured that most of the time I will be placed at an inpatient site, and those places are mostly walkable. I figured that in the worst case scenario I will need a car for up to like 4 months total, each of which will be spread throughout the year. Best case scenario I will only need the car for like a month or less over the next year.In this case wouldnt it cost less to just rent? However, the unpredictability of my placements makes me want to just own...EDIT: Thinking even ubering might be an option because depending on the site it would cost 20 a day per commute, 5 days a week.EDIT 2: Almost 50day for some sites if I uber. Hopefully I wont be placed there.EDIT 3: Thanks for all the replies!  <response>: I think Id just buy a cheap car with the intention of selling it in a year if necessary. Your M3 year is going to be busy and stressful, sometimes with odd hours. You dont want to have to rely on Uber to get you to the hospital at 5 am so you can pre-round on surgery patients. Having your own reliable transportation will be one less thing you need to worry about, which is probably a more valuable benefit than you realize right now.
