Car salesman to IB?

I graduated from a semi-target school in 2020 with a 3.15 GPA (3.67 major GPA). I didn't have any offers when I graduated and spent the summer of 2020 applying to jobs with no luck. I took a job selling cars as a way to make some money while I was searching. Its now been two years and I'm still selling cars, and I hate it. I've applied to more jobs than I can count, and while I've gotten multiple super day invites, I have yet to lock down an offer. Originally, I was only looking at roles at BBs and other prestigious firms, but now I'll apply to just about anything. One thing that's really holding me back is my lack of relevant work experience on my resume. It's also becoming increasingly difficult to try to leverage my degree as I am now over 2 years out of college. 

I have considered going back to school for an MSF, but I am about to turn 24 and wouldn't be able to start an MSF until fall of 2023 which means I'll be 25 by the time I finish, and I don't really want to wait another year and a half to start my professional career. I have also considered taking the CFA exams but I don't know how useful that would be given my lack of experience. 

I'm feeling pretty lost at this point and I don't know what my next move is. I am trying to determine if I should just write-off the rest of this year and prepare for an MSF, or continue applying to jobs. One thing is for sure, I can't continue working as a car salesman. I hate it with a passion. I'd appreciate any guidance for my situation. Is an MSF the best move at this point? Even though I'm two years removed from college, could I network my way to an offer? Is there any way I could leverage my experience as a car salesman to potentially break into S&T? Or should I just keep firing out applications and hope that my luck changes? 

Any and all advice welcome.
