I can't really think of any that have been in continuous production. I can think of dozen examples of where a manufacturer revives an old name plate and is a radical departure from the original, 6th gen Dodge Charger for instance, but I'm drawing blanks in terms of continuous production. The Skyline/GTR is a special and I would count it as automotive royalty since it has outlasted much of the competition from Europe, North America and domestically in Japan.
