Some girls model with cars simply to make a few extra bucks on the side while they go to college. Not Crystal Leigh (@XoCrystalLeigh). She really lives this, man! Although she's only 21, she's fully committed to making modeling her career. As a result, she's been featured on the cover of Super Streetbike. She's earned a spread in Lowrider. And she's landed on calendars by K&N Exhaust, MT Collisions, and California Glamour Girls. She's also worked at car events, done promo work for a number of companies, and starred in a music video or two. No wonder she's already been able to start doing this for a living.
