It was down to 7 or 10 for me as well. I'd say they're as good as each other, but I went for 7 because it's 'the before they went mainstream (ie pre-crash)' option.
<insert pretentious music albums example here>
I loved 10, but 6 was the kicker for me. It was a longer series, and included gems such as the ?1500 coup?s that weren't Porsches, mums' test, Weismann vs. TVR, snipers vs. sports cars and the SLR vs. Boat race. The convertibles in Iceland episode was a downer, but the rest of it was top stuff.
Series 8 is when the decline started, but was still good. Series 9 was the beginning of the end when they decided to scrap all the reviews they had planned before Hammond got hurt.
Real tossup between 4 and 5 for me. The original race and cheap car challenged vs. those ideas perfected with the Ferrari race and Porsche challenge. Went with 5.
I didn't want to vote on this, as it seems a bit silly to choose a favorite series. I can think of things I like in all of them, including even the most recent series 14.
I'm going to say that I like more videos out of Series 5, though that's a bit unfair due to its having more episodes.
I'm going to say that 12 comes second in my not a vote
