Watch him change the tire, it's worth the wait.
If you have heard of the Citroen DS at all, then you have no doubt heard how innovative, different and strangely wonderful it was. This would be true if it debuted today, but in 1955 it was positively alien, in a good way. So here we have a rather long video of Jay Leno showing us all about the car, with that kind of length being necessary in order to show everything that was amazing about the car. Many of the features never caught on, despite being excellent.
Jay's DS is a particularly nice example of the car as well, and this sort of thing always makes it more enjoyable to watch.
