there was a barndoor samba just unearthed in Europe (Germany i believe) a few months ago. it was literally feet from where the PO mowed and just forgot about it while it rotted away. the new owner found it when assessing the property and the PO sold it happily. apparently in Germany you can get fined big time if you have rotting cars. some sort of environmental policy.
Now, 'it' is subjective. more like 'them'. the bus was hardly there. the VIN and M code plates were though
the new owner is planning a sympathetic resto. last i followed up, they itemized the pieces and propped them up to roughly resemble the shape of a bus.
This was the worst i've heard of.
