I hadn't been posting links to Top Gear on YouTube when I watch each Series because they disappear so fast. Here's a current playlist that has a lot of episodes gathered together. Right from Series 1 to Series 23. It's missing a few episodes and while I found most of those on uploaded by other YouTube users, who knows if they won't show up here at some point. I'll be checking back to fill in the gaps I have. I know the episodes from Series 4 were just uploaded, you can tell from the date posted. The thing is they weren't there in August, I was looking for them then. That's the thing about YouTube, stuff can linger for years, or be gone in a few hours. I don't know who long they'll be up there. You can watch them or download them with the Firefox YouTube download app. I did the latter to continue watching Top Gear in reverse order. I have DVDs though Series 10 coming from the library, a set each week or so, but after that there are no other DVDs to watch. Now I have Series 1 to Series 9 ready to watch. It's not DVD quality but it's better than nothing.
