I'll add my name to the list.
I've got a 1981 R80G/S. I'm the 5th owner. Purchased new by a local auto mechanic. Sold to somebody in Tucson. Then supposedly went to a BMW mechanic in the Denver area. Then sold to a guy who lived in Silverthorn CO who advertised it for sale on IBMWR. That's where I saw it and bought it back in 1999. When the local mechanic, original owner saw it he recognized it as his. To prove it he produced the original bill of sale w/ right VIN number. Small world, eh? That's where we tied the rest of the bikes ownership history together.
Maybe I'll get unlazy and get a picture up here one day. I've added a PD tank, works shock, Jesse bags, Rick Meyer saddle (guaranteed no less comfortable than stock). Been through 2 transmission. Near as I can tell it's got 160K miles on it. I've ridden from the tip of Baja to Prudoe Bay AK.
