Here's one that's a bit different from what's been posted so far.

This is my 1985 Mongoose ATB. I had started a resto-mod job on it after finding it in a thrift store, but I was offered a trade for it in "as is" condition shortly afterwards, so I haven't made any progress since these pics. I do still have it, but it will be boxed up and shipped off soon.

These first 3 pics are in as found condition.






And here are some pics of the progress I had made on it before agreeing to the trade and stopping.
