The one on Cuba was great, it showed you how to make brake fluid out of brown sugar, alchohol and shampoo, and showed how to make a new quarter panel using nothing but a roof from a wrecked Caddy and a hammer!
The one on Australia was good too, it was about the outback and he talked about the land trains.
Detroit, well either you’ll love it or hate it, it is a view of the once great city through the eyes of a British car expert.
My favorite one though it Italy, he interviews this guy who has the greatest job EVER! The Ferrari test driver.

All in all, if you have some time go ahead and check them out.
