Well, not entirely true: Huminori Watanabe is a plumber and he drives a Nissan Skyline KGC110 GT-R imitation.

If you look careful enough you will notice this KGC110 has a SOHC L20A or L24 inline six and not the DOHC S20 that featured in the GT-R. Still a very cool car to do your plumbing in. :D :D

Suppose you are an American, work for the airforce and (of course) move to a base in Japan somewhere in 1979, what car would you drive then?
A Nissan Skyline C110 of course!

Long haired Nissan Skyline KGC110
This long blonde haired American owned a 1974 Nissan Skyline 2000 GTX complete with a set of periodically correct Hart Racing rims back in 1982.
