I don't remember that one. I had an Advent 201. Worked well for years but eventually the rubber belts gave out. I wasn't finding much to listen to by then so it wasn't a big deal.
The Nakamichi Dragon was an autoreverse cassette deck, but rather than just reversing the direction of the tape, it had a mechanism to automatically eject the tape, flip it, then load it back up and start playing the other side.
Very cool to watch (back then.)
