As shown in the pic... there's a rough line of "glue" for some reason... I think some glue spilt on it while it was sitting in the garage, not sure. But anyway, I'm pretty sure there's no crack or anything underneath. People around my area (SE Melb) are more then welcome to come and inspect anytime.
Give me a call on 0402346691. I'm looking for $100 firm simply because of the line. Quick sale...
