College student's first car auto repair needed

I'm needing some help getting a vehicle fixed for my neice. She's in her first year of college and will be turning 19 later this month. Currently she is having to hitch a ride back home on the weekends. I'm giving her my Jeep Liberty to start off with, but it currently needs motor repairs, totalling around $500...but if enough is raised, we will replace the motor so the vehicle will be like new. This girl is amazing, she has won countless academic awards since grade school and graduated valedictorian in high school .. She's now attending her first year of college, studying to be a pharmacist... and she's 45 minutes from home. I am so proud of her and I want her to have a ride. She deserves it so much, and I want to make it happen for her. Any donations are greatly appreciated.
