My neighbor just up the block was moving, and parked his Weber Spirit out at the curb next to a pile of junk a couple months back. I figured it was a goner, but thought I could salvage some parts or maybe make a table out of it, so I wheeled it home. The tank was empty and the battery was dead, but once I dealt with those two things it worked perfectly! Cleaned it up and sold it to a very happy friend for $250.
It is strange what people throw away!
