Sunglasses, I store in the pocket to the right of the shifter. Change - I boycott tolls so not an issue. Random small stuff I store in the rear cupholders between the seats. If you need anything bigger that won't fit in the glovebox, stick a box in the back. You didn't exactly buy an SUV here :)
As far as the rear wiper, I ordered mine from Amazon. http://www.amazon.com/gp/product/B001KS2PXQ/ref=oh_aui_detailpage_o00_s02?ie=UTF8&psc=1
