You are definitely not the only one that saw it on YT. I was wondering where it went as well a couple weeks ago when I went searching for it again. It was a cool video. I believe it had the "greased incline" demonstrations/ comparisons of the Eagle VC 4-wheel drive system vs. either Subaru or Toyota.
As I have no laserdisc player, I'd love to get a digital version of the video as well if it ever turns-up.
"More Tough Action from American Motors" -- a delightfully '80s Marlboro-man-esque, tough-guy motto. I know you can hear the guy's voice as you read those words...
