What it means
SIDE (and LEFT SIDE or RIGHT SIDE) means the car was hit on the side: doors, fenders, pillars, sills or wheels. Side impacts can bend the B-pillar and the sill, which are structural, and can damage the suspension if a wheel was hit.
What it means for a buyer
Look at the door gaps and the wheel alignment in the photos. Side curtain airbags and seat airbags may have deployed. A hit to the wheel area can mean suspension and steering parts too.
