oooh I love bumper to bumper stripes! Sometimes it is hard to keep the car "balanced" vinyl wise. Wider stripes on the top sides of the car need to be balanced with something on the lower sides IMO. If you have the stripes and a big swoosh or something on the sides of the car it makes it look too top heavy to me. Not sure where to get Cobalt specific designs, most seem to be pretty universal.
