ive seen all the SPEED series, they not bad..... clarkson is pretty young in them, there was also a few speed series made that aired once and were took off... one was about the space shuttle....they tested the rocket engine and clarkson was told that everytime they test it, it WILL rain in an hr...and true to their word it did indeed rain....
the one where he also drives a 32 ford which in his words "LOOKS LIKE A PIECE OF LEGO" is also a great episode....he runs it at bonneville speed flats to over 200mph...
