I might be the only person on this entire forum who, until yesterday, had never seen "Jay Leno's Garage."
I mean, I knew it existed, but I had never seen an episode... so last night as I was surfing around on youtube as I often do, I clicked on it–and I loved it! In fact I liked it so much I watched probably 8-10 episodes in a row! I don't know if it's scripted, but it seems like Jay (and his guest, if there is one) just basically talks off the top of his head, very casually... but he knows his stuff. He gets into detail, but not so much that you have to be a gearhead to understand what he's talking about. Very well done, very informative, just the right amount of info to keep "car guys" interested but not so much to overwhelm those who don't know as much about cars.
I'm a Jay Leno fan, I'm a car fan, I'm a youtube fan... finally I got with the program, so to speak, and put all three together... I'll be watching more episodes again tonight.
And if it's possible that there are actually others out there like me who had never seen it, check it out.
