If you ask the Society of Automotive Engineers of Japan, the greatest milestones in their industry range from the ABS system on the '71 Nissan President to the Subaru Impreza WRX STI... and 238 more.

Some are on the silly side— wasn't the Toyoglide a license-built GM Powerglide clone, for example?— but the whole collection makes for fascinating reading for the true gearhead.
