Hi everyone, iv been driving for 8 years now, and the only car i have trouble head checking is this corolla stivo. Im finding it very hard to left head check because there is this fat creamy plastic thingy between the rear windows and left hand side window. Almost got a car accident quite a few times now, such a blind spot. Iv driven so many other cars and i dont even have that problem. The most easiest car to head check is the marage haha. If anyone have that problem just say so, i hope im not the only one. SORRY FOR PUTTING UP A STUPIT QUESTION HAHA!!
