I’m 19 y/o full time college student with a part time job looking to purchase a new car and have two people in my life recommending two options on the matter. One person is telling me to finance a car and the other telling me to find one off of fb marketplace. Luckily the one telling me to buy off of marketplace has been able to fix my car (multiple times) and offered to look at the cars that we would potentially look at. I am still on my father’s insurance but will have to pay my share of the bill every month (around $300) so i was wondering what would be the best option. I have about $7k saved as of now just worried spending everything i have saved all at once and not having an emergency fund.
