I had to laugh following this thread. The idea of buring parts really hit home. A buddy and I were at my in-laws building a retainer wall along a creek with sacks of Ready-Mix concrete. I noticed something in the creekbank shining and dug out a nearly perfect chevy hubcap. Further investigation uncovered a buried '55 Chevy Belair convertible. Of course it is way past restoring now but...what a shame! We did scrounge a second hubcap, both wiper arms and some chrome, all in very good condition.
