Some things you just gotta know. And this is one thing that is possible. Fills the whole back and my dog had to sit on the floor behind the front seats, but she was OK with that. Once unboxed from its Tesla packaging you can carefully lift and fit it in the back of the car with seats folded down. I placed it with curvature upward like a cup, won't lie flat through the seat opening but fits tilting up the "front leading edge" of the windshield and propping it up in the opening. OF COURSE lots of boxes and foam packaging strategically propped to keep all resting stresses off the glass and nestled like an egg in a nest accommodates sharp road bumps... rode with it like that for 300 miles home to trusted glass shop near me to install. Tesla would have charged ~ $300 to have it shipped there instead.. but since SC is free for me did the trip... Just know that you can!
