Almost all of Top Gear is now available on MotorTrend On Demand. I say almost all because MotorTrend only lists 172 available while Wikipedia says there are 202. Still enough for some serious binging. The Clarkson, Hammond, and May era is available along with the new version featuring Chris Harris and co. Not sure which 10 episodes are missing but seasons 2-25 are listed. All in the original 1 hour BBC versions too.
