Go to the feature on Bring-A-Trailer for some real discussion on this little beast. http://bringatrailer.com/2015/07/14/integra-swapped-rutledge-woods1983-honda-civic-wagon/
Yup it is a factory colour, That interior is in a creepy way correct also, although the bucket seats redone to match are not factory. Although correct, that interior....yellow and tans....... I can't believe me of all people am saying this but a short drive with those colours inside.... I'd be tempted to kick a puppy!
When dating my ex-wife back in the early '90s, her parents had a Civic wagon that looked identical to this, same color, same vintage, etc (except for the seats). Always thought it was a cool car.
