Download Utorrent
1.goto
http://www.utorrent.com/ and hit the "get utorrent button"
2. download a good media player. I use VLC...seems to play everything.

Hit windows, then the "not to far away location" download
3. Goto FinalGear. They are the source for Top Gear, Fifth Gear, and Top Gear Australia.
http://www.finalgear.com/
For topgear...go to the shows button and then click top gear.
http://www.finalgear.com/shows/
Next, find the season you want, then find the episode you want and click it.
Then, goto "click here for the torrent from Mininova"
After every season, all the episodes are joined to form a "season download"
If you dont want the whole season, when utorrent asks which once you want, click on them.
Only problem is utorrent still thinks you want everthing and work it as if you are downloading everything but only the episodes you clicked on get saved. Soo....just download the whole season as its the best and most effiecent way.
I don't know what else you might need. Good luck.
