long story short...my coworker accidently drove thru the shop door with his truck...he used plexiglass to replace the windows...so i capitolized on the left over plexi for my Yaris...this winter has been really killing my mpg...upper 30s which is unheard of for me in this car. So i'm hoping to make it back into the lower 40s. I left the lower opening a little bigger then i would normally do, I dont plan to remove these for summer.
