Today’s Top Gear can be found here. If Mininova says the torrent doesn’t exist, refresh the page. Seems the torrent hasn’t made it out onto all of their different servers as of the time of this post (they’re having growing pains due to their increasing popularity).

You can also try getting it via this magnet link (works with µTorrent, Azureus, and others) or HTTP (free forum registration required).
