I know this is supposed to be vehicles that will fit a piece, but I can tell you that a GMC Terrain absolutely will NOT fit a 4' wide piece much less 8' long. The first time I needed plywood from the BORG I asked them to cut it in half thinking that a 4x4 piece would fit. NOT A CHANCE! I had to stand it up in front of the back seat and even then it was very tough to get in.
So bottom line - if you need to carry 4'x8' sheets, DON'T get a GMC Terrain!!
