No need to belabor this – you really just need to watch. The three-wheeled hero car is a BuBu 501 by Mitsuoka, and yes, it's being chased and attacked by a group of ninja. On roller skates. Doing stunts. (Don't miss the absurd roller disco-style maneuver that has one ninja pull another through his legs for no discernible reason whatsoever.)
Even if you've seen this vintage Japanese footage before, you're going to want to revisit it, so follow the jump and let the awesome wash over you.
